Some Heusler compounds were predicted to have half-metallic electronic structures [1], which are important properties in spintronics. Then Co-substituted Mn3Ga Heusler films, which exhibit perpendicular magnetic anisotropy (PMA) and the magnetic transition from PMA to in-plane magnetic anisotropy (IMA), were considered to be potential spintronic materials [2,3]. In this work, we have investigated electronic structures of Mn3-xCoxGa films by employing synchrotron radiation-excited soft X-ray absorption spectroscopy (XAS) and soft X-ray magnetic circular dichroism (XMCD). According to Co 2p XAS and XMCD, the substituted Co ions in Mn3-xCoxGa consist of ferromagnetic metallic Co clusters and divalent Co ions with disordered magnetic moments. Mn 2p XAS and XMCD show that Mn ions at both the octahedral and tetrahedral sites are nearly divalent, reflecting non Jahn-Teller ions, and that the magnetic moments of Mn ions are polarized along the ordered magnetic moments of the substituted Co ions. Angle-dependent Co 2p XMCD results agree with the weak PMA-IMA magnetic anisotropy transition with increasing Co content. This work reveals that the magnetic anisotropy transition in Mn3-xCoxGa is determined mainly by the ferromagnetic metallic Co clusters of the substituted Co ions.

The development of antiferromagnetic (AFM) spintronics is an active field with great potential for improving energy consumption, reducing interference and decreasing sizes when compared to traditional spintronics. This requires the development of novel concepts and functionalities which allow control over the properties of a device containing an AFM layer.
We present in this work a new device concept in which the spin configuration of an AFM insulator (FeF2) can be modified taking advantage of spin-orbit coupling (SOC) existing in heavy metals (HM) such as W or Pt. The device consists of a trilayer: HM|AFM|FM, therefore the top FM interface can be used to monitor the changes in the AFM spin configuration.
We performed Magneto-Optical Kerr effect (MOKE) to measure the FM hysteresis loops as a function of temperature (T) and applied current (I). We found that the exchange bias (EB) and coercivity (Hc) produced at the AFM-FM top interface can be strongly modified by a current (I) passed through the HM|AFM bottom interface. This shows that an active spin-orbit torque (SOT) is produced at the HM|AFM bottom interface that reaches the AFM|FM top interface and modifies the reversal of the FM layer. Temperature-dependent control experiments using normal metals (NM) such as Au in NM|AFM|FM and without AFM in HM|FM confirm that the effect is produced by the SOT induced by the HM and is not caused by thermal heating, Oersted field or other potentially spurious effects.

Manipulation of Exchange Bias Using Spin Orbit Torque

The transport of magnons in materials with topological non-trivial ground state has been investigated in various platforms (ferro- and antiferromagnets) and is characterized by anomalous mechanisms such as the thermal Hall effect and the magnon Nernst effect. Usually, these investigations are done in the framework of the Linear Spin Wave Theory and the interactions between magnons are ignored. In fact, due to the bosonic nature of magnons, such interactions can have a dramatic impact on the magnon lifetime [Chernyshev, AL et al., Phys. Rev. Lett. 117, 187203 (2016)] and band structure [Mook et al., Phys. Rev. X 11, 021061 (2021)], as recently demonstrated. In other words, these interactions are ubiquitous and can cause the alteration of the energy bands and the transport properties of the system, including damping and topological phase transitions [Y.S. Lu et al., Phys. Rev. Lett. 127, 217202 (2021)]. In this work, we investigate the influence of magnon-magnon interactions on the anomalous transport of magnons in a topologically non-trivial honeycomb antiferromagnet. Focusing on the magnon spin Nernst effect, we uncover the impact of these interactions on the magnon lifetime, band structure and anomalous transport upon increasing the temperature.

Impact of Interactions on Topological Magnonic Transport

Synthetic antiferromagnets (SAFs) are of interest in a wide variety of spintronic applications owing to their net zero magnetisation and inherent tunability arising from control over complex stacking sequences [1]. They show very fast domain wall (DW) motion in response to spin torques [2].
Here we describe measurements of the current-driven DW motion in each of the separate magnetic sublattices of a SAF with structure Ta/[Ru/Pt/CoB/Ru/Pt/CoFeB]×5/Ru/Pt which displays both perpendicular magnetic anisotropy (PMA) and the Dzyaloshinskii-Moriya interaction (DMI). The thickness of the Ru layers is tuned to provide AF coupling between each pair of layers. The thicknesses of the alternating CoB and CoFeB layers are tuned to give net zero magnetisation (as measured by SQUID magnetometry) at a wide range of fields up to ~50 mT.
The magnetic films were grown on Si3N4 membranes and imaged with scanning transmission x-ray microscopy (STXM). They were patterned into 2 µm wide wires with Cu leads attached to each end. The distinct chemical composition of the two sublattices means that we could use the element specificity of STXM to observe the CoFeB separately by imaging at the Fe L3 edge, whilst contrast at the Co L3 edge is dominated by the other sublattice of CoB layers. Inverted domain structures observed at these two edges with XMCD-STXM are shown in Fig. 1, confirm the SAF ordering of the layers. Current pulses drive domain wall motion, as shown in Fig. 2, with average velocities up to ~ 40 m/s achieved at current densities as low as 3 × 1011 A/m2. These results demonstrate a low depinning current and fast motion compared to comparable FM multilayers we have previously studied, suggesting that domain walls in SAF heterostructures are superior to their ferromagnetic equivalents for low energy consumption racetrack technologies.

Current Driven Domain Wall Motion in a Synthetic Antiferromagnet Multilayer

Europium (Eu) metal has a body centered cubic crystal structure which, upon a paramagnetic-to-helical magnetic transition, undergoes a body centered tetragonal distortion. The magnetic helix appears below Néel temperature (TN) of ~90 K, and the presence of a magnetic field gives rise to conical helimagnet [1,2]. We have prepared Eu metal thin films on Si (001) substrates using Eu metal as a target by pulsed laser deposition (PLD). The transport measurement shows the helical antiferromagnetic transition at 88 K, and a thermal hysteresis reveals the first-order nature of the phase transition. We present the magnetoresistance (MR) of Eu thin films when the magnetic field (B) is applied both out-of-plane and in-plane. We found, at temperatures below TN, the MR is positive whereas above TN the MR is negative. We also observed the hysteretic oscillation above 30 K and below the Néel temperature. The hysteretic oscillations observed in the MR is believed to be associated with the change in the distribution of the antiferromagnetic domains in Eu caused by the interplay of the applied magnetic field and the strain in the films.

Magnetoresistance in Helical Antiferromagnet Eu Metal Thin Films

Transition metal nitrides with ferrimagnetism have recently attracted attention because of their skyrmionic functionalities at room temperature [1,2], and the topological Hall effect (THE) was observed for Mn based transition metal nitrides such as Mn4N thin films [3,4]. The conventional spin texture for the film is collinear with perpendicular magnetic anistoropy, which is remarkably sensitive to the growing temperature as well as substrate-induced strain [5,6]. Therefore, these characterisitcs of the Mn4N warrants further study how the spin texture is modulated by the method of elemental doping, and it is our expectation that the turnability of spin textures of the films could allow us to realize possible skyrmionic devices that work under no external magnetic field. In this study, we investigated the THE for the sputter-deposited (111)- and (110)-oriented Mn4(N,B) films aiming the control of topological spin textures by elemental-doping of B [7].
Figures 1 shows the representative THE for the 111-oriented Mn4N film without B at 300K. The THE component was extracted from the total AHE component, suggesting the presence of non-coplanar spin texture for the films at room temperature. Figure 2 shows the measurement temperature (T) dependence of ρxyTHE/ρxyAHE ratio for the films with and without B. The ratio increased at lower T, suggesting the stabilization of non-coplanar spin textrue at lower T. In addition, supression of THE was observed by B for all T. These results show a dilution effect in the spin frustration state with topological spin texture by B. Conversely, slight increase of THE was observed by B in the case of 110-oriented films. Therefore, B in the antiperovskite systems such as Mn4N could acts as an efficient suppressor or booster of frustrated exchange interactions between Mn atoms.

Tailored non collinear magnetic structure in 111

Antiferromagnetic materials opened up a new avenue of research with potential use in spintronic devices [1]. Compared to their ferromagnetic counterparts antiferromagnets exhibit faster dynamics, insensitivity to the external magnetic fields, and absence of stray fields promising higher integration density.
Some functionalities of the antiferromagnetic spintronic devices such as readout using anisotropic magnetoresistance or reorientation of magnetic axis using current-induced spin-orbit torque [2] are directly derived from their ferromagnetic counterparts whereas other functionalities are unique to the antiferromagnets. One of these is the Quenching of the antiferromagnet into high resistivity states using electrical and optical pulses which was recently discovered in epitaxially grown thin CuMnAs films [3]. This effect is based on the change of the magnetic structure of the antiferromagnet induced by the application of high energy pulse driving the system to the vicinity of Néel temperature and its subsequent fast cooling resulting in quenching of the highly resistive disordered magnetic state. The observed changes of resistivity reach tens of percent at room temperature and even 100 percent at low temperatures and exceed by two orders of magnitude the change of the resistivity based on anisotropic magnetoresistance induced by the reorientation of the spin axis [2].

In this contribution, we provide an overview of detailed experimental characterization of quenching of CuMnAs using a single ultrashort laser pulse for excitation. We focus on the optimization of the electrical readout response of the Hall-bar devices with regard to the size and position (Fig.1) of the laser spot, pulse length, and fluency. It provides an overview of the response for CuMnAs films with varying thickness and substrate material. Lastly, this contribution evaluates the effects of permanent damage caused by laser pulse excitation with proposed damage mitigation techniques.

Characterization of laser pulse induced quenching of resistivity of antiferromagnetic CuMnAs

Room-temperature skyrmions have been presented as potential candidates for encoding information bits in several types of new spintronic devices [1]. There have been many recent progresses allowing to stabilize sub-100 nm skyrmions at room temperature in crystalline ferromagnetic thick layers or in (amorphous) thin magnetic multilayers (MML) [2]. In most case, at least in extended films or large structures, the application of relatively large perpendicular field (a few 10 mT) is needed which might be unfavorable for most of the anticipated skyrmion based devices. Hence, the stabilization of zero-field isolated skyrmions or skyrmion lattices is an important step towards application. There are recent works demonstrating isolated zero-field skyrmions stabilized due to interlayer exchange in polycrystalline [3], epitaxial [4] or exchange biased [5] trilayers. Here we demonstrate a new approach showing that room-temperature zero-field skyrmion lattices can be stabilized in MML. We develop a system in which perpendicular magnetic anisotropy, chiral order and bias field strength, through a non-magnetic spacer, can be adjusted simultaneously. Typical stacking sequence is schematically presented in Figure 1 (a). The samples have been characterized first by standard magnetometry (Fig. 1b). Relying on the interlayer electronic coupling to an adjacent bias magnetic layer with strong perpendicular magnetic anisotropy (uniform configuration), we demonstrate by Magnetic Force Microscopy that the remnant wormy-stripe “as-grown” domains (Fig. 1d) can be turned into skyrmion lattice phase (Fig. 1c). The skyrmion density and size can be modified by finely tuning the thicknesses of the layers allowing the control of the parameters related in the stabilization of the lattices.

Zero field room

Magnetic skyrmions is a vortex like nanosized spin swirling texture with particle like property [1]. In the past decade, magnetic skyrmion has triggered great interest as component in futuristic magnetic memory devices due to its topological property, smaller size (few nm) and efficient current driven motion. The chiral cubic β-Mn type (Co0.5Zn0.5)20-xMnx (3 ≤ x ≤ 7) alloys are fascinating as they allow the fine tuning of size and stability of skyrmions in wide temperature range with composition [2]. Among (Co0.5Zn0.5)20-xMnx alloys, magnetic properties of the Co7Zn7Mn6 alloy are of renewed interest due to the detection of two independent skyrmion phases (SkX): (i) a conventional thermodynamically stable SkX below helimagnetic to paramagnetic transition temperature (TC ~ 213 K) and (ii) a disordered skyrmion phase above spin glass transition (Tg ~ 23 K) [3-4]. In spite of much progress made on the investigation of exotic magnetic field-temperature phase diagram of Co7Zn7Mn6 helimagnet, the nature of its underlying magnetic interactions still remains elusive. Thus an elaborate in-field critical behavior study of skyrmion hosting polycrystalline cubic β-Mn type Co7Zn7Mn6 chiral magnet based on magnetic isotherms measured in the vicinity of ordering temperature is presented. The critical exponents β, γ and δ for spontaneous magnetization, initial magnetic susceptibility and critical M-H isotherm, respectively are evaluated through the modified Arrott plot, Kouvel-Fisher method and critical isotherm analysis. The estimated critical exponents β = 0.382(1), γ = 1.386(2) and δ = 4.628(1) follow Widom equality and magnetic scaling equations of state. The values of these exponents corroborate that the critical behaviour of Co7Zn7Mn6 system is akin to that of three-dimensional (3D) isotropic nearest-neighbour Heisenberg ferromagnet in which the attractive extended type short-range interactions between spins decay with distance r as J(r) ~ r-4:94.

In field critical behaviour of β

We investigated the spin-orbit torque (SOT) switching of the single CoTb layer with or without the heavy metals (Pt and W) in different thicknesses to identify the self-torque effects generated in the CoTb layer. The generation of self-torque heavily depends on the thickness of CoTb. The SOT switching was not observed for a single CoTb layer with 3nm in thickness, suggesting self-torque may be quite weak in a very thin film. A deterministic SOT switching can be obtained for a single 9 nm CoTb layer. The amplitude of the self-torque generated in CoTb is comparable to the Pt/Co case with the same switching polarity as the Pt/Co one. When 3 nm CoTb has deposited on Pt or W underlayer, the Jc is smaller in W/CoTb than that of Pt/CoTb, which can be attributable to a high spin hall angle of W and negligible self-torque of CoTb. On the other hand, when the CoTb is increased to 9 nm, the Jc of W/CoTb is significantly increased and becomes higher than that of Pt/CoTb. The enhanced Jc of W/CoTb may result from the opposite sign of spin-orbit torque generated in W and CoTb. Since the self-torque generated in 9 nm CoTb becomes substantial, the competition of spin-orbit torque between W and CoTb occurs, leading to a high Jc. We define the switching efficiency η=(2Hk2-Hx2)1/2*Mst/Jc based on the macrospin model 1, in which Hk and Hx are anisotropy field and applied magnetic field along the x-direction. The variations of η with the layer structure are shown in Table 1. The addition of SOT from Pt and self-torque from CoTb leads to enhanced switching efficiency when the thickness of CoTb is increased. On the other hand, the competition of SOT from W and self-torque in TbCo of W/CoTb devices was revealed by increasing the thickness of CoTb. We further confirm this interplay by reversing the stack order, that is, CoTb/W, in which the efficiency is substantially enhanced.

Effects of self torque in rare earth

Magnetic multilayers are material systems that offer a high degree of tunability with respect to their magnetic and electronic properties. These are essential for today’s spintronics and magnonics-based magnetic applications [1], [2]. The Dzyaloshinskii-Moriya interaction (DMI) [3] is one of the interesting phenomena in such multilayers that give rise to the presence of magnetic skyrmions under certain conditions even at room temperature. Pt/Co is one of the most promising classes of the multilayers that contributes to a significant DMI due to the different characters of Pt/Co and Co/Pt interfaces [4]. The performance of the films may vary depending on the substrates, deposition temperature, layer thickness, and other factors in the Pt/Co multilayers. The thermal stability can be significantly increased and the magnetic anisotropy of Pt/Co multilayers can be controlled by adding spacer layers between two Co layers [5].
In our study, we investigate magnetic bubbles in Pt/Co-based multilayer thin films. The bubbles have been expanded using an external magnetic field both in-plane and out-of-plane. In presence of the in-plane field, bubbles expand asymmetrically as observed in Fig.1(a). The in-plane field-dependent velocities of two opposite chiral domain walls are measured as shown in Fig. 1(b). The asymmetry of bubble expansion is found to be influenced by the thickness of Co which gives us information about the intrinsic chiral properties of the system. Mumax simulations are performed to understand underlying behavior. The study is important for race track memory applications.
