Abstract
A spin current magnetization rotational element includes: a ferromagnetic metal layer; a spin-orbit torque wiring configured to extend in a first direction perpendicular to a lamination direction of the ferromagnetic metal layer and formed on one surface of the ferromagnetic metal layer; and a ferromagnetic electrode layer formed outside the ferromagnetic metal layer on any of surfaces of the spin-orbit torque wiring in a top view from the lamination direction. A direction of magnetization of the ferromagnetic metal layer is changeable by spin-orbit torque generated by a spin-orbit interaction in the spin-orbit torque wiring and an influence of spin diffused from the ferromagnetic electrode layer.
