摘要：

Quantum oscillations of the transverse magnetoresistance have been observed in the heavy fermion metal UPt3 in fields up to 24.5 T applied in the basal plane, providing the first observation of the quasiparticle Fermi surface above the metamagnetic transition. The observed quasiparticle masses remain strongly renormalised in the high field state, ranging from 30 to approximately 100 times the bare electron mass.
