| 1 | Onset of the Meissner effect at 65 K in Fe Se thin film grown on Nb-doped Sr TiO_3 substrate显示文摘We report the Meissner effect studies on an Fe Se thin film grown on Nb-doped Sr Ti O3 substrate by molecular beam epitaxy. Two-coil mutual inductance measurement clearly demonstrates the onset of diamagnetic screening at 65 K, which is consistent with the gap opening temperature determined by previous angle-resolved photoemission spectroscopy results. The applied magnetic field causes a broadening of the superconducting transition near the onset temperature, which is the typical behavior for quasi-two-dimensional superconductors. Our results provide direct evidence that Fe Se thin film grown on Nb-doped Sr Ti O3 substrate has an onset TC* 65 K,which is the highest among all iron-based superconductors discovered so far. | Zuocheng Zhang Yi-Hua Wang Qi Song Chang Liu Rui Peng K.A.Moler Donglai Feng Yayu Wang | 2015 | Science Bulletin2015，60，14： | 10 |
