Abstract

One branch has been detected in the de Haas-van Alphen (dHvA) experiments in both the normal and superconducting mixed states of URu₂Si₂ and UPd₂Al₃ with an anisotropic superconducting energy gap. The corresponding Dingle temperatures increase and the cyclotron effective masses decrease in the mixed states. An anisotropic energy gap with a line node has been discussed from the angular dependence of the dHvA amplitude in the mixed state.
