We report transport evidence of nonreciprocal response in a topological-insulator/normal-metal Bi0.91Sb0.09/Pt hybrid structure. In the presence of an in-plane magnetic field, we observe a direction-dependent critical current asymmetry, which points to the occurrence of a supercurrent rectifying effect. We demonstrate that the observed magneto-transport anomaly can only arise from the topological surface states that induce a strong correlation between the spin polarization of carriers and the direction of supercurrent.
