摘要：

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 100m(0). 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. (C) 2000 Elsevier Science B.V. All rights reserved.
