摘要：
Within the quasiclassical approximation we have studied the thermodynamics and the thermal conductivity in the vortex state in nodal Superconductors (sc). Recent angle dependent magnetothermal conductivity results indicate a gap function Delta(k) corresponding to f- wave sc in Sr2RuO4 and d- wave sc in CeColn(5) and kappa-(ET)(2)Cu(NCS)(2) respectively. More recently it is shown that Delta(k) in both YNi2B2C and PrOs4Sb12 have point nodes described by hybrid s+g wave gap function.
