Spin-orbit-torque (SOT)-driven perpendicular magnetization switching has attracted great attention for designing energy-efficient, high-density, and thermal-stable storage devices. As field-free deterministic of is not allowed in conventional heavy metals or topological insulators where spin polarization limited to the in-plane direction, transition metal dichalcogenides (TMDs) emerge as current platforms due their low-crystal symmetries. However, present studies using TMDs are restricted...
