Abstract

We present our studies of the factors affecting soft magnetic properties and giant magnetoimpedance effect in thin amorphous and nanocrystalline microwires. We showed that the magnetoelastic anisotropy is one of the most important parameters that determine magnetic softness and GMI effect of glass-coated microwires  and annealing can be very effective for manipulation the magnetic properties of amorphous ferromagnetic glass-coated microwires. Considerable magnetic softening and increasing of the GMI effect is observed in Fe-rich nanocrystalline FINEMET-type glass-coated microwires after the nanocrystallization.

Prof. A.P. Zhukov graduated in 1980 from the Physics-Chemistry Department of the Moscow Steel and Alloys Institute (presently National University of Science and Technology). In 1988 he received Ph.D. degree from the Institute of Solid State Physics (Chernogolovka) of the Russian Academy of Science, in 2010- Doctor of Science (habilitation) in Moscow State “Lomonosov” University. Present employment: Ikerbasque Research professor at the Department of the Materials Physics of the University of Basque Country, Spain. Current fields of interest: amorphous and nanocrystalline ferromagnetic materials, magnetic micro-wires, giant magneto-impedance, giant magnetoresistance, magnetoelastic sensors. He has published more than 400 referred papers in the international journals (total number of citations of A. Zhukov’s papers, updated January 02, 2016: 4819, Citation H-index = 36). A. Zhukov, edited conference proceedings, chaired Donostia International Conference on Nanoscaled Magnetism (DICNMA), III Joint European Magnetic Symposia, few sessions at MMM and Intermag Conferences, gave a number of invited talks at few international conferences. He is an associate Editor of IEEE Magnetic letters and International Journal on Smart Sensing and Intelligent Systems, member of several editorial boards and various committees of International Conferences, guest Editor of J. Magn. Magn. Mater, Phys. Stat. sol (A) and (C). A. Zhukov Edited a book “Novel Functional Magnetic Materials”, wrote two books: “Magnetic properties and applications of ferromagnetic microwires with amorphous and nanocrystalline structure” and “Magnetic sensors based on thin magnetically soft wires with tuneable magnetic  properties and its applications”, few book chapters (the last one for the       Handbook of Magnetic Materials ed. by Prof. K. Buschow ), articles for the “Enciclopedia of NanoScience and Nanotechnology” and  “Enciclopedia of  Sensors”. In 2000 he funded Small Company- TAMAG, presently coordinating ERA-Net project and participating in FP7 programme.
