A simple, reliable, and electrically controllable way to develop complementary spin–orbit logic devices is highly desired. In this work, controllable field-free spin–orbit torque (SOT) switching is demonstrated in the Pt/IrMn/Co/Ru/CoPt/CoO/MgO heterojunction at room temperature, which makes it an a...
