Abstract
A spin-orbit torque magnetization rotating element includes a spin-orbit torque wiring and a laminated body laminated on the spin-orbit torque wiring. The laminated body includes a first ferromagnetic layer independently having an axis of easy magnetization in a first direction, a nonmagnetic antiferromagnetic coupling layer, and a second ferromagnetic layer independently having an axis of easy magnetization in a second direction, in order from the side of the spin-orbit torque wiring, and the first direction crosses the second direction.
