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 ANGSTROM and a second magnetic film layer made of Co-rich Co-Ni-Fe having a thickness of 10 to 100 ANGSTROM , 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 ANGSTROM interposed therebetween. The non-magnetic metal film layer is of a metal, for example, Cu, Ag, Au, Pt, Ru or Re. (NiACo1-A)BFe1-B, NiAFe1-A or NiACo1-A is used as a material of the first magnetic film, and (CoCNi1-C)DFe1-D is used as a material of the second magnetic film. |
