CONTROL METHOD OF MAGNETIZATION IN FE-CR THIN FILM MULTILAYERS

摘要

A control method of magnetization in Fe-Cr thin film multilayers can control the location of atom on the Fe thin-film in the Cr atom evaporation and control the magnetization of the Fe-Cr multi-layered thin film. The interface structure of the Fe-Cr multi-layered thin film is transformed by changing the location of the Cr atom at the interface of the inter-layer of the Fe-Cr multi-layered thin film. The Cr atom is positioned between the hollow site and bridge site of the Fe(001) surface. The Fe-Cr multi-layered thin film has the magnetization of -1.8~1.4 muB according to the location of the Cr atom. The Fe-Cr multi-layered thin film is formed by the molecular beam epitaxy method.
