Spin-transfer induced switching in magnetic nanopillars

Summary form only given, as follows. The author reviews the basic experimental findings of spin-induced magnetic switching in sub-100 nm 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.
