Theory and Applications of Spin Torque Nano-Oscillator: A Brief Review

Abstract

We present a brief review of spin torque nanooscillator, which has triggered extensive research interests in the field of nanomagnetism and applied spintronics in recent years. The underlying physical mechanism governing the spin torque nanooscillator is the spin momentum transfer effect, where the angular momentum of itinerant electrons can be passed to localized magnetic moments. The typical device architectures and design of spin torque nanooscillator have been reviewed in this paper, with a particular focus on potential applications of spin torque nanooscillator in the fields of nanotechnology, computing, and biotechnology.Contents of Paper
