Abstract
An example magneto-resistance effect element includes a magnetization layer and a free magnetization layer of which magnetization direction changes depending on an external magnetic field. A spacer layer is located between the magnetization layer and the free magnetization layer, and has an insulating layer and an electric conductor passing current therethrough in a layer direction of the insulating layer. A diffusive electron scattering layer is disposed on said free magnetization layer for scattering diffusive electrons. The scattering layer includes a first nonmagnetic layer and a second nonmagnetic layer containing a first element and a second element, respectively, and a mixing layer disposed at a boundary between the first and second nonmagnetic layers and containing the first and second elements. The mixing layer has a thickness of 0.5 nm or more and 1.5 nm or less.
