The electrical switching of magnetization through spin–orbit torque (SOT) 1 holds promise for application in information technologies, such as low-power, non-volatile magnetic memory. Materials with strong spin–orbit coupling, such as heavy metals 2 – 4 and topological insulators 5 , 6 , can convert...
