Enhanced field-free current-induced magnetization switching by interlayer exchange coupling with insulating spacer layer

We investigated field-free current-induced perpendicular magnetization switching in Pt/Co/AlOx/Co/Ta structures by varying the thickness of an insulating spacer layer. A field-free spin–orbit torque switching is realized through the antiferromagnetic interlayer exchange coupling (IEC) between the bo...
