Abstract:
1. A magneto-resistance effect element, comprising: a fixed magnetization layer of which magnetization direction is substantially fixed to a single direction; a free magnetization layer of which magnetization direction changes depending on an external magnetic field; a spacer layer located between the fixed magnetization layer and the free magnetization layer, and having an insulating layer and an electric conductor passing current therethrough in a layer direction of the insulating layer; and a diffusive electron scattering layer disposed on the free magnetization layer for scattering diffusive electrons, the diffusive electron scattering layer including 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 having a thickness of 0.5 nm or more and 1.5 nm or less.
