从理论上研究了超导体中的自旋霍尔效应。从铁磁体注入超导体的自旋在Sc中产生准粒子自旋和电荷电流，在横向上产生电荷和自旋电流，在超导体的侧边附近积累自旋和电荷不平衡。预测在超导态的低温下，自旋霍尔效应的侧跳和斜散射机制中的自旋和电荷积累信号将发生极大的增强。
Spin Hall effect in a superconductor is theoretically studied. The spin injection from a ferromagnet into a superconductor creates quasiparticle spin and charge currents in SC, which generate charge and spin currents in the transverse direction to accumulate spin and charge imbalance near the side edges of a superconductor. A giant enhancement of spin and charge accumulation signals in the side jump and skew scattering mechanisms of the spin Hall effect is predicted to occur at low temperatures in the superconducting state.
