Spin Transfer Torques

Understand

This tutorial article introduces the physics of spin transfer torques in magnetic devices.

• We provide an elementary discussion of the mechanism of spin transfer torque, and review the theoretical and experimental progress in this field.
• Our intention is to be accessible to beginning graduate students.
• This is the introductory paper for a cluster of "Current Perspectives" articles on spin transfer torques published in volume 320 of the Journal of Magnetism and Magnetic Materials.
