SPIN ORBIT TORQUE TYPE MAGNETIZATION ROTATION ELEMENT, SPIN ORBIT TORQUE TYPE MAGNETORESISTANCE EFFECT ELEMENT, AND MANUFACTURING METHOD OF SPIN ORBIT TORQUE TYPE MAGNETIZATION ROTATION ELEMENT

摘要

To provide a spin orbit torque type magnetization rotation element capable of causing magnetization rotation without applying an external magnetic field without increasing a current flowing through a spin orbit torque wiring layer.SOLUTION: A spin orbit torque type magnetization rotation element includes a spin orbit torque wiring layer extending in an X direction, and a first ferromagnetic layer stacked on the spin orbit torque wiring layer. The first ferromagnetic layer has shape anisotropy, and has a major axis in a Y direction orthogonal to the X direction in a plane in which the spin orbit torque wiring layer extends. In the plane in which the spin orbit torque wiring layer extends, the magnetization easy axis of the first ferromagnetic layer is inclined with respect to the X direction and the Y direction orthogonal to the X direction.SELECTED DRAWING: Figure 1
