Spin current magnetization rotational element, spin-orbit-torque magnetoresistance effect element, magnetic memory, and high-frequency magnetic element

摘要

The present disclosure is directed to a spin current magnetization rotational element, a spin-orbit-torque magnetoresistance effect element, a magnetic memory, and a high-frequency magnetic element which can efficiently generate a pure spin current and reduce a reversal current density. The spin current magnetization rotational element includes: a spin-orbit torque wiring extending in a first direction; and a first ferromagnetic layer laminated in a second direction which intersects the first direction, wherein the spin-orbit torque wiring includes at least one rare gas element of Ar, Kr, and Xe.
