摘要： A magnetoresistance effect element has a pair of ferromagnetic layers with a middle non-magnetic metallic layer interposed therebetween. The middle non-magnetic metallic layer has lamination structure of non-magnetic metallic thin films formed of at least two kinds of non-magnetic metallic materials. In the lamination structure of the non-magnetic metallic thin film, Fermi energies of the non-magnetic metallic thin films disposed on interface sides of the ferromagnetic layers has a value closer to a Fermi energy in a direction of spin whose electron spin dependent mean free path is long among Fermi energies of the ferromagnetic layers. A non-magnetic metallic thin film is disposed between such two non-magnetic metallic thin films. Difference in Fermi energy between non-magnetic metallic thin films made of two kinds of non-magnetic metallic materials is 0.5 eV or more. By the use of such a middle non-magnetic metallic layer, while the thickness thereof is as thin as possible, exchange coupling between ferromagnetic layers can be small. Thus, resistance change sensitivity can be enhanced.
