Abstract

The f-electron systems of the cerium and uranium compounds have attracted attention in the context of heavy fermion and anisotropic superconductivity. We clarified an itinerant f-electron nature for UPt₃ by the de Haas-van Alphen experiments, detecting heavy conduction electrons with 100m₀. The dHvA oscillation was also observed clearly in both the normal and superconducting mixed states in CeRu₂, URu₂Si₂ and UPd₂Al₃. An anisotropic energy gap with a line node for URu₂Si₂ was discussed from the angular dependence of the dHvA amplitude in the mixed state.
