Abstract

We have done the transverse magnetoresistance and the de Haas-van Alphen (dHvA) experiments in UPt3. The magnetoresistance increases in the whole field direction. UPt3 is thus a compensated metal, possessing no open orbits. As for the dHvA experiment, we have observed at least three new branches. One of them is in the basal plane and the others are around the [0001] direction. The branches with dHvA frequencies of 2.7×10 Oe and 4.9×10 Oe in the field along [0001] possess large masses of 40–50 m0. These results have been discussed on the basis of the 5f-itinerant Fermi surface model.
