Spin-Hall effects in a Josephson contact

Abstract

The Josephson tunneling through a 2D normal contact with the spin-orbit split conduction band has been studied in the diffusive regime. Linearized Usadel equations for triplet components of the pairing function revealed a striking similarity to the equations of spin diffusion driven by the electric field in normal metals. Consequently, we predict that the out-of-plane spin-Hall polarization accumulates towards lateral sample edges and the in-plane polarization is finite throughout the entire normal region. At the same time, the spin-Hall current is absent in the considered case of the stationary Josephson effect.
