摘要：

We have used high pulsed magnetic fields to 50 T to observe de Haas-van Alphen oscillations in the heavy fermion antiferromagnet UCd11, which has a strongly enhanced value of the electronic specific-heat coefficient (gamma = 803 mJ/mol K-2). The low-temperature magnetization shows the existence of two magnetic phase transitions. The presence of quantum oscillations above the first transition indicates that UCd11 has a coherent Fermi liquid, although there is little or no change in the Fermi-surface topology on passing through the second transition.
