Abstract
A magnetoresistance effect element includes a non-magnetic substrate, a ferromagnetic dispersion layer or a ferromagnetic layer, and a non-magnetic metal film. The ferromagnetic dispersion layer is a layer of a ferromagnetic metal or alloy that is independently and dispersedly formed on the substrate. The alternative ferromagnetic layer is a layer of a ferromagnetic metal or alloy that is formed on the substrate with a textured surface. The non-magnetic metal film is made of at least one atomic element having a non-soluble relation with the ferromagnetic metal or alloy, and is formed on the non-magnetic substrate and the ferromagnetic dispersion layer or the ferromagnetic layer.
