摘要

The spin injection effects from C-type antiferromagnetic Nd_0.35Sr_0.65MnO₃ (NSMO) to superconductor YBa₂Cu₃O_7-δ (YBCO) are investigated via the measurement of temperature dependent resistivity with input current from 10^-2mA to 90 mA. The superconducting transition temperature (T_co) of YBCO decreases with increasing current but at a higher rate with larger thickness of NSMO. Two spin states below T_co are identified as non-equilibrium spin-state and pair-breaking state judging from the width of transition. In particular, the transition from former to later one is observed with NSMO = 30 nm at the current of 30 mA.
