Spin-transfer induced switching in magnetic nanopillars

Abstract

I will review the basic experimental findings of spin-induced magnetic switching in sub-100nm magnetic nanopillar spin valves. Issues include the basic physics of a spin-current-induced torque on a nanomagnet, sample fabrication techniques, and device properties in terms of current-induced magnetic excitation and magnetic switching dynamics. Potentials for future applications in magnetic memory technology and related challenges will also be briefly discussed. © 2005 IEEE.
