Possible Sign-Reversing s-Wave Superconductivity in Co-Doped BaFe2As2 Proved by Thermal Transport Measurements
Thermal transport measurements have been performed on single-crystalline Co-doped BaFe2As2 down to 0.1 K and under magnetic fields up to 7 T. Significant peak anomalies are observed in both thermal conductivity and thermal Hall conductivity below Tc as an indication of the enhancement of the quasiparticle mean-free path. Moreover, we find a sizable residual T -linear term in thermal conductivit...
متن کاملMultiband superconductivity in BiS2-based layered compounds.
A mean-field treatment is presented of a square lattice two-orbital-model for [Formula: see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula: see text]) and electron doping x. With the help of ...
متن کاملAnisotropic s-wave superconductivity in MgB2
It has recently been observed that MgB2 is a superconductor with a high transition temperature. Here we propose a model of anisotropic s-wave superconductivity which consistently describes the observed properties of this compound, including the thermodynamic and optical response in sintered MgB2 wires. We also determine the shape of the quasiparticle density of states and the anisotropy of the ...

15 صفحه اولConventional superconductivity and charge-density-wave ordering in Ba1xNaxTi2Sb2O
We have investigated the low-temperature physical properties of BaTi2Sb2O and Ba1−xNaxTi2Sb2O (x=0.05, 0.1, 0.15, 0.2, 0.25, 0.3) by means of muon spin rotation (�SR) and SQUID magnetometry. Our measurements reveal the absence of magnetic ordering below TDW=58 K in the parent compound. Therefore the phase transition at this temperature observed by magnetometry is most likely due to the formatio...
