Three-terminal spintronics devices for integrated circuits

Spintronics-based integrated circuits open up a new pathway toward ultralow-power and high-performance computing systems. Three-terminal spintronics devices, which achieves fast and reliable operation due to a relaxed control of parameters, have attracted increasing attention. We here review our recent studies on spin-orbit torque induced magnetization switching, which can be applied to the write operation of the three-terminal devices. We demonstrate the switching in a new device geometry and in a new material system.
