| 英文摘要 | The order parameter of the recently-discovered ferric arsenide family of superconductors remains uncertain. some early experiments on polycrystalline samples suggested line nodes in the order parameter, however later experiments on single crystals have strongly supported fully-gapped superconductivity. an absence of nodes does not rule out unconventional order: pi phase shifts between the separate fermi sheets and time-reversal symmetry-breaking components in the order parameter remain possibilities. one test for unconventional order is scanning magnetic microscopy on well-coupled polycrystalline samples: d- or p-wave order would result in orbital frustration, leading to spontaneous currents and magnetization in the superconducting state. we have performed scanning squid microscopy on smfeaso0.85 and ndfeaso0.94f0.06, and in neither material do we find spontaneous orbital currents, ruling out p- or d-wave order. |
