1 Jul 2015 | Abstract: | We report the Meissner effect studies on an FeSe thin film grown on Nb doped
SrTiO3 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 FeSe thin film grown
on Nb doped SrTiO3 substrate has an onset TC ~ 65 K, which is the highest among
all iron based superconductors discovered so far. | Source: | arXiv, 1507.0129 | Services: | Forum | Review | PDF | Favorites |
