1 Introduction Current induced magnetization switching (CIMS) can be realized in a perpendicularly magnetized heavy metal (HM)/ferromagnetic metal (FM) bilayer through a current-induced in-plane spin-orbit torque (SOT), although the determination of magnetization switching still needs an in-plane external magnetic field.[1-8] To achieve the SOT-induced magnetization switching without such an in-plane external magnetic field, the device usually has a particular design to break the symmetry,...
