Thermal conductivity in superconducting borocarbides LuNi2B2C and YNi2B2C
arXiv:cond-mat/0210364
Abstract
We have recently proposed the s+g wave model for superconducting borocarbides. In spite of a substantial s-wave component, this order parameter exhibits the H^1/2 dependent specific heat and a thermal conductivity linear in H in the vortex state. This is characteristic for nodal superconductors when T, Î<< Îwhere Îis the quasiparticle scattering rate and Îthe maximum superconducting gap. Here we investigate the thermal conductivity parallel to the c- and a- axis in a magnetic field tilted by θfrom the c- axis and rotating within the a-b plane.
