Correlation between Phase-Structural State and Magnetic Characteristics of Spin-Valve Systems Based on Fe, Co and Au

Abstract

This paper presents the results of investigation of phase-structural state, magneto-optical and magneto-resistive properties of multilayer spin-valve films structures on the basis of Fe, Co and Au. It was found that annealing of the samples up to Ta = 600-720 K leads to the formation of limited solid solution (s.s.) (Au, Co(Fe)) based on fcc-Au that considerably influences on the magnetic properties of the systems. The conditions and formation procedure of the most heat-stable systems with maximum values of magneto resistance, sensitivity to magnetic field changes and induction of demagnetization were found.
