Spin-valve structures with Co-Tb-based multilayers

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