Abstract
A spin-current magnetization rotational element includes a spin orbit torque wiring extending in a first direction and a first ferromagnetic layer disposed in a second direction intersecting the first direction of the spin orbit torque wiring, the spin orbit torque wiring having a first surface positioned on the side where the first ferromagnetic layer is disposed, and a second surface opposite to the first surface, and the spin orbit torque wiring has a second region on the first surface outside a first region in which the first ferromagnetic layer is disposed, the second region being recessed from the first region to the second surface side.
