摘要：

We investigate the spin Hall magnetoresistance (SMR) in niobium (Nb) attached to Y3Fe5O12 near the superconducting critical temperature (T-c) of Nb. The SMR vanishes after cooling the sample below T-c, and recovers if the temperature is raised. When a magnetic field larger than the critical field of Nb is applied, the SMR re-emerges with an enhanced magnitude even if the temperature is below T-c. The experimental results demonstrate that the SMR could be completely suppressed by the coupling between superconducting condensation and spin-orbit interaction in superconductors. In addition to the fundamental physics on the charge-spin interactions in superconductors, our work adds a different dimension to superconducting spintronics. (C) 2015 WILEY-VCH Verlag GmbH & Co.
