Magnetoimpedance of nanostructure Сu—Fe₃O₄—СеО₂—Fe₃O₄—Сu

Abstract

The work ofnanoscale structure Cu—Fe₃O₄—CeO₂—Fe₃O₄—Cu on alternating current was studied A positive and negative sign of tunneling magnetoimpedance (TMI) at different conditions were observed. The greatest magnitude of TMI = 754% correspon-ded to the largest spin electron polarization in the Fe₃O₄ layers, which was egual to 93,8%.
