Title:
スピン軌道トルク型磁気抵抗効果素子及びスピン軌道トルク型磁気抵抗効果素子の製造方法
Document Type and Number:
Japanese Patent JP7183703
Kind Code:
B2
Abstract:
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
