Topological Insulator-Based High Efficiency Switching of Magnetic Unit, Method and Application

Unmet Need: The invention meets the need for improved magnetic random access memory, racetrack memory, and spin logic devices. The present state of the art of electrical current by spin-orbital torque (SOT) consists of a single heavy metal layer (e.g., W or Ta) in contact with a ferromagnetic layer, which acquires perpendicular magnetic moment suitable...
