Room-Temperature Spin-Orbit Torque Switching Induced by a Topological Insulator
Room-Temperature Spin-Orbit Torque Switching Induced by a Topological Insulator
The strongly spin-momentum coupled electronic states in topological insulators (TI) have been extensively pursued to realize efficient magnetic switching. However, previous studies show a large discrepancy of the charge-spin conversion efficiency. Moreover, current-induced magnetic switching with TI can only be observed at cryogenic temperatures. We report spin-orbit torque switching in …
