RESUMO
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 CeCoIn5 and k-(ET)2Cu(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.
