Dr. Ovari has an extensive experience in the investigation of wire-shaped rapidly quenched amorphous magnetic materials, starting with the amorphous glass-coated microwires, and continuing with the amorphous submicron wires and nanowires. His focus was on the practical aspects of such materials, e.g., their use as sensing elements in various types of magnetic sensors, or as magnetic domain wall conduits for magnetic logic applications. He pursued postdoctoral research at the Institute of Materials Science in Madrid (ICMM-CSIC), at Ecole Polytechnique Montreal, and at the Wolfson Centre for Magnetics Technology at Cardiff University, UK. After his return to the National Institute of Research and Development for Technical Physics in Iasi, Romania, Dr. Ovari has continued to study various aspects of amorphous glass-coated microwires, such as the inter-domain wall in amorphous microwires (Physical Review B, vol 76, 214433, Dec. 2007). He was a member of the team that produced and studied for the first time ever the rapidly quenched amorphous submicron wires (Journal of Applied Physics, vol. 107, 09A301, May 2010) and nanowires (Journal of Applied Physics, vol. 109, 063902, Mar. 2011). These new, ultrathin cylindrical magnetic amorphous nanomaterials have become the main focus of his research activity (Rev. Sci. Instrum., vol. 82, 094701, Sep. 2011; IEEE Trans. Magn., vol. 47, 3513, Oct. 2011; Rev. Sci. Instrum., vol. 83, 064708, Jun. 2012). The mobility, pinning and displacement of domain walls in rapidly quenched nanowires have been also thoroughly investigated (J. Appl. Phys., vol. 113, 17A304, May 2013; J. Appl. Phys., vol. 115, 17A329, May 2014; and J. Appl. Phys., vol. 117, 17D502, May 2015). The basic interactions in such materials, their overall hysteresis behavior (magnetization reversal), and their magnetic anisotropy have been of great interest as well (IEEE Trans. Magn., vol. 50, 2006904, Nov. 2014; IEEE Trans. Magn., vol. 50, 2007304, Nov. 2014; and J. Magn. Magn. Mater., vol. 410, 100, Jul. 2015). Some of most important advances in this field have been put together in a book chapter published in 2015: “Magnetic nanowires and submicron wires prepared by the quenching and drawing technique” in Magnetic Nano- and Microwires: Design, Synthesis, Properties and Applications (M. Vázquez, Ed.), Woodhead Publishing (Cambridge), pp. 199-223, 2015. More recently, Dr. Ovari has begun to investigate cylindrical nanowires with nanocrystalline structure made from amorphous precursors (Crystals, vol. 7, 48, Feb. 2017), alongside the micromagnetic analysis of magnetization reversal in amorphous glass-coated nanowires (AIP Adv., vol. 9, 105316, Oct. 2019) and the use of electrical currents to drive the domain walls in cylindrical magnetic wires (Sci. Rep., vol. 9, 5868, Apr. 2019). Dr. Ovari has published over 130 papers, three book chapters, and co-authored two patents on the applications of amorphous magnetic glass-coated wires. He was the principal investigator for several projects.
