Current,instead of magnetic field,induced magnetization switching is very important for future spintronics in information storage or/and information processing.As one of the effective current-induced magnetization methods,spin-orbit torque(SOT)has aroused considerable interest because it has low-power consumption and can improve the device endurance.Normal metal(NM)/ferromagnetic metal(FM)are the common materials used for SOTs,where the NM denotes the materials with strong spin-orbit coupling such as Pt,Ta,...
