Abstract:
To provide a magnetic memory capable of performing stable recording while suppressing occurrence of an inversion error. Provided is a magnetic memory including a spin orbit layer in which a spin-polarized electron is generated by a current, a magnetic memory element having a laminated structure including a magnetic layer in which a magnetization direction changes according to information to be recorded and an insulating layer, and provided on the spin orbit layer, and a voltage application layer for applying a voltage to the magnetic layer via the insulating layer, in which the voltage application layer applies a voltage to the magnetic layer at a same time as the current flowing in the spin orbit layer to change magnetic anisotropy or a magnetic damping constant of the magnetic layer.
