Abstract

The problem of spin current across a ferromagnetic/normal metal/ferromagnetic junction is formulated. It is shown that the spin current is controlled by the phase difference across the junction. Under zero bias, J_z is time-independent and J_z is sinusoidal function, where J_z is the S_z current along z -direction. Under a dc bias, J_z and |J_z + iJ_z| are sinusoidal and the phase of the latter is in front by π.
