Ultralow Electrical Current Driven Field‐Free Spin‐Orbit Torque Switching of Magnetic Tunnel Junctions by Topological Insulators

Ultralow Electrical Current Driven Field‐Free Spin‐Orbit Torque Switching of Magnetic Tunnel Junctions by Topological Insulators

Abstract Spin‐orbit torque‐driven magnetic random‐access memory (SOT‐MRAM) is one of the promising candidates for next‐generation memory technologies beyond Moore's law. Due to its separation of writing and reading channels, the 3‐terminal device design significantly improves the device enduran...
