Abstract
The role of preparation conditions and parameters of the layered structure on the magnetoresistive properties of Fe20Ni80/Fe50Mn50 and Fe20Ni80/Fe50Mn50/Fe20Ni80 films with exchange coupling have been investigated. It was found that relative position of the Fe20Ni80 and Fe50Mn50 layers as well as presence of the high frequency electric bias of the substrate during film deposition affect the efficiency of the exchange interaction. Dependences of the exchange bias field and anisotropic magnetoresistance on the heat treatment conditions for the films with different layered structures were analyzed.
