Nodeless superconductivity in Ca3Ir4Sn13: evidence from quasiparticle heat transport
Nodeless superconductivity Ca3Ir4Sn13 evidence quasiparticle heat transport
2012/2/27
We report thermal conductivity measurements down to 50 mK on Ca$_3$Ir$_4$Sn$_{13}$ single crystals, in which superconductivity with $T_c \approx 7$ K was claimed to coexist with ferromagnetic spin-flu...
Calorimetric Evidence for Nodes in the Overdoped Ba(Fe$_{0.9}$Co$_{0.1}$)$_{2}$As$_{2}$
Calorimetric Evidence
2010/11/25
We present low-temperature specific heat of the electron-doped Ba(Fe0.9Co0.1)2As2, which does
not show any indication of an upturn down to 400 mK, the lowest measuring temperature. The
lack of a Sch...
