Abstract

The influence of the thickness of layers on magnetic properties of {Co-Tb}_n, {Co-Tb}_n-Co, and {Co-Tb}_n-Co-Cu-Co films was investigated. The dependencies of magnetic hysteresis and magnetoresistive properties of {Co(1 nm)-Tb(1 nm)}n-Co(5 nm)-Cu(L_Cu)-Co(5 nm) structures on the thickness of the {Co-Tb}_n layer and Cu spacer were obtained. The possibility of creating of spin-valve structures based of multilayered {Co-Tb}_n films with in-plane magnetic anisotropy was shown.
