Patent ID: 11832531

Abstract:
A spin-orbit torque magnetization rotational element includes: a first insulating layer with first and second openings; a first conductive portion formed inside the first opening; a second conductive portion formed inside the second opening; a spin-orbit torque wiring located in a first direction and extends in a second direction over the first and second conductive portions; and a first ferromagnetic layer located on the side opposite to the first insulating layer in the spin-orbit torque wiring, wherein the first conductive portion includes a first surface facing the spin-orbit torque wiring, a second surface facing the first surface and is located at a position farther from the spin-orbit torque wiring than the first surface, and a side surface connecting the first surface and the second surface, and the side surface includes a continuous major surface and a third surface inclined or curved and is discontinuous with respect to the major surface.
