Abstract

In this work peculiarities of the hysteresis properties formation in permalloy layers included in Fe20Ni80/FeMn/Fe20Ni80 films were investigated. Temperature dependencies of magnetization reversal parameters were analyzed in the temperature range 5-300 K for samples with various FeMn thickness (2÷4 nm). Conditions of the exchange bias emergence were determined. Magnetic history was shown to have a significant effect on the magnitude and the character of the exchange bias.
