Abstract

As CMOS technology begins to face significant scaling challenges, considerable research efforts are being directed to investigate alternative device technologies that can serve as a replacement for CMOS. Spintronic devices, which utilize the spin of electrons as the state variable for computation, have recently emerged as one of the leading candidates for post-CMOS technology. Recent experiments have shown that a nano-magnet can be switched by a spin-polarized current and this has led to a number of novel device proposals over the past few years. In this paper, we provide a review of different mechanisms that manipulate the state of a nano-magnet using current-induced spin-transfer torque and demonstrate how such mechanisms have been engineered to develop device structures for energy-efficient on-chip memory and logic.
