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.
