Abstract:
1. A magnetic element comprising: a pinned layer; a spacer layer, the spacer layer being nonmagnetic; a free layer, the spacer layer residing between the pinned layer and the free layer; a spin scattering layer, the free layer residing between the spin scattering layer and the spacer layer, the spin scattering layer being configured to more strongly scatter majority electrons than minority electrons; a heat assisted switching layer, the spin scattering layer residing between the free layer and the heat assisted switching layer, the heat assisted switching layer for improving a thermal stability of the free layer when the free layer is not being switched; wherein the magnetic element is configured to allow the free layer to be switched due to spin transfer when a write current is passed through the magnetic element.
