Abstract
Provided is a spin current magnetization rotational element including: a spin-orbit torque wiring that extends in a first direction and is configured to generate a spin current; a first ferromagnetic layer that is laminated in a second direction intersecting the spin-orbit torque wiring and is configured for magnetization direction to be changed; and a first perpendicular magnetic field applying layer that is disposed to be separated from the spin-orbit torque wiring and the first ferromagnetic layer, the first perpendicular magnetic field applying layer being configured to apply an assistant magnetic field assisting a magnetization rotation of the first ferromagnetic layer.
