Abstract
This spin current magnetization rotational element includes a second ferromagnetic metal layerhaving a variable magnetization orientation, and spin-orbit torque wiring, which extends in a direction that intersects a direction perpendicular to the surface of the second ferromagnetic metal layer, and is connected to the second ferromagnetic metal layer, wherein the spin resistance of a connection portion of the spin-orbit torque wiring layerthat is connected to the second ferromagnetic metal layeris larger than the spin resistance of the second ferromagnetic metal layer
