摘要：
We have performed the de Haas-van Alphen (dHvA) experiments in UPt3, A new branch has been observed in a relatively wide angle region. It has a large cyclotron effective mass of 80 m(0) and the dHvA frequency is 5.66 x 10(7) Oe for the field along the [0001] direction. The new branch most likely corresponds to the main electron Fermi surface in the 37th band of the 5f-itinerant band model.
