摘要： The spin injection effects from C-type antiferromagnetic Nd{sub 0.35}Sr{sub 0.65}MnO{sub 3} (NSMO) to superconductor YBa{sub 2}Cu{sub 3}O{sub 7−δ} (YBCO) are investigated via the measurement of temperature dependent resistivity with input current from 10{sup −2 }mA to 90 mA. The superconducting transition temperature (T{sub co}) of YBCO decreases with increasing current but at a higher rate with larger thickness of NSMO. Two spin states below T{sub 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. 出版者： United States 出版日期： 2015-05-07 出處： Journal of applied physics, 2015-05, Vol.117 (17) 資源來源： AIP Journals (American Institute of Physics) 識別號： ISSN: 0021-8979 識別號： EISSN: 1089-7550 識別號： DOI: 10.1063/1.4914534
