摘要:
In a spin valve type magnetoresistance effect film, an antiferromagnetic layer is made of MxMn100−x wherein M represents at least one selected from Ru, Rh, Re, Pt, Pd, Au, Ag, Fe, Ni, Ir and Cr, and 15≦x≦58 (unit of x: atomic %), and a protective layer formed thereon is made of at least one selected from Rh, Ru, Zr and Ti. With this arrangement, a magnetoresistance effect film highly excellent in thermal stability and small in deterioration of the MR ratio, as well as a magnetoresistance effect type head having such a magnetoresistance effect film can be obtained.
