Exchange coupling film magnetoresistance effect device magnetoresistance effective head and method for producing magnetoresistance effect device |
摘要 |
An exchange coupling film of the present invention includes a substrate and a multilayer film. The multilayer film includes: a ferromagnetic layer and a magnetization rotation suppressing layer provided adjacent to the ferromagnetic layer for suppressing a magnetization rotation of the ferromagnetic layer; and the magnetization rotation suppressing layer includes an Fe-M-O layer (where M=Al, Ti, Co, Mn, Cr, Ni or V).
