Spin current in a superfluid Fermi-liquid in an electric field

JETP 75, 479 (1992) [ZhETF 102, 876 (1992)]

The interaction of magnetic moments of moving Fermi-particles with an external electric field creates a dissipation-free spin current in the superfluid state. In the superfluid ³He-B the influence of the electric field can be revealed by experiments with spin supercurrent between two vessels with homogeneously precessing magnetization.
