Recent demonstrations of magnetization switching induced by in-plane current in heavy metal/ferromagnetic heterostructures (HMFHs) have drawn great attention to spin torques arising from large spin–orbit coupling (SOC). Given the intrinsic strong SOC, topological insulators (TIs) are expected to be...
