    • note
    • Fabian and Das Sarma have investigated the spin current and spin populatin dynamics in the presence of magnetic field transients. Their approach is based on the semiclassical Boltzmann theory in the linear response regime. The work of Brataas (Ref.) uses a rotating magnet to study the pumped spin current from a spin battery. Since the rotating magnet introduces a spin flip mechanism the spin current is not conserved. What we have done in this paper is to investigate the average spin current at finite bias in the present of a periodic magnetic field. A steady spin current is found in contrast to the transient spin current studied in the work by Fabian and Das Sarma. Our approach is full quantum mechanical and the photon assisted tunneling for spin current is observed. In our approach the spin current is conserved which differs from the work of Brataas
