Dependence of the superconducting transition temperature (T-c) and critial superconducting pressure (Pc) of the pressure-induced superconductor beta-(BDA-TTP)(2)I-3 [BDA-TTP = 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathiapentalene] on the orien...

Thermal conductivity tensor has been measured using single crystalline Co-doped BaFe2As2 down to 0.1 K and under magnetic fields up to 7T. We observe peak anomalies both in the thermal conductivity and the thermal Hall conductivity in the supercon...
