We studied giant magnetoimpedance (GMI) effect in magnetically soft amorphous Co-rich microwires in the extended frequency range. From obtained experimentally dependences of GMI ratio on magnetic field and different frequencies we estimated the penetration depth and its dependence on applied magnetic field and frequency

A. Zhukov, Dpto. Fisica de Materiales, Fac. Quimicas, UPV/EHU, 20018 San Sebastian, Spain

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.
