摘要
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 rootH dependent specific heat and a thermal conductivity linear in H in the vortex state. This is characteristic for nodal superconductors when T, Gamma much less than Delta where Gamma is the quasiparticle scattering rate and Delta the maximum superconducting gap. Here we investigate the thermal conductivity parallel to the c- and a-axis in a magnetic field tilted by theta from the c-axis and rotating within the a-b plane.
