Nonequilibrium spin-transfer torque in SFNFS junctions

Superconductivity 2009-11-11 v2

Abstract

We report theoretical results for the nonequilibrium spin current and spin-transfer torque in voltage-biased SFNFS Josephson structures. The subharmonic gap structures and high voltage asymptotic behaviors of the dc and ac components of the spin current are analyzed and related to the spin-dependent inelastic scattering of quasiparticles at both F layers.
