Abstract
There is provided a magnetoresistance effect element which is a multilayer structure body wherein a first magnetic film layer made of Ni-rich Ni-Co-Fe having a thickness of 10 to 100 .ANG. and a second magnetic film layer made of Co-rich Co-Ni-Fe having a thickness of 10 to 100 .ANG., which are different from each other in coercive force, are integrally laminated with a non-magnetic metal film layer having a thickness of 10 to 100 .ANG. interposed therebetween. The non-magnetic metal film layer is of a metal, for example, Cu, Ag, Au, Pt, Ru or Re. (Ni.sub.A Co.sub.1-A).sub.B Fe.sub.1-B, Ni.sub.A Fe.sub.1-A or Ni.sub.A Co.sub.1-A is used as a material of the first magnetic film, and (Co.sub.C Ni.sub.1-C).sub.D Fe.sub.1-D is used as a material of the second magnetic film.
