Abstract
A spin-orbit-torque type magnetization rotating element includes: a spin-orbit torque wiring extending in a first direction; and a first ferromagnetic layer laminated on the spin-orbit torque wiring, wherein the spin-orbit torque wiring includes a metal oxide whose electrical conductivity properties exhibit a metallic behavior with respect to temperature, and an oxygen concentration in a region on the first ferromagnetic layer side and an oxygen concentration in a region opposite to the first ferromagnetic layer are asymmetrical with respect to a center of the spin-orbit torque wiring in a thickness direction thereof.
