| Abstract: | We investigate the spin Hall magnetoresistance (SMR) in niobium (Nb) attached to Y3Fe5O12 near the superconducting critical temperature (Tc) of Nb. The SMR vanishes after cooling the sample below Tc, 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 Tc. 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. (© 2015 WILEY‐VCH Verlag GmbH &Co.
