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, has a major axis in the X direction. In a plane in which the spin orbit torque wiring layer extends, the easy magnetization axis of the first ferromagnetic layer is inclined with respect to the X direction and a Y direction orthogonal to the X direction.SELECTED DRAWING: Figure 1
