A study of heat transport in NbSe2 down to Tc/100 throughout the vortex state, providing further evidence for multiband superconductivity (MBSC) was reported. Measurements of heat transport in the vortex state of NbSe2 at low temperatures reveal the existence of highly delocalized quasiparticles down to fields close to Hc1. This was in striking contrast with what was expected in a s-wave superconductor where well-separated vortices should support only localized states, as was observed in V3Si.
