Abstract
Provided is a spin-orbit-torque magnetization rotational element that suppresses re-adhesion of impurities during preparation and allows a write current to easily flow. The spin-orbit-torque magnetization rotational element includes a spin-orbit torque wiring that extends in a first direction, and a first ferromagnetic layer that is located on a side of one surface of the spin-orbit torque wiring. A side surface of the spin-orbit torque wiring and a side surface of the first ferromagnetic layer form a continuous inclined surface in any side surface.
