Title: De Haas{endash}van Alphen effect, magnetic transitions, and specific heat in the heavy-fermion system UCd{sub 11}

Abstract

We have used high pulsed magnetic fields to 50 T to observe de Haas{endash}van Alphen oscillations in the heavy fermion antiferromagnet UCd{sub 11}, which has a stongly enhanced value of the electronic specific-heat coefficient ({gamma}=803 mJ/molthinspK{sup 2}). The low-temperature magnetization shows the existence of two magnetic phase transitions. The presence of quantum oscillations above the first transition indicates that UCd{sub 11} has a coherent Fermi liquid, although there is little or no change in the Fermi-surface topology on passing through the second transition. {copyright} {ital 1999} {ital The American Physical Society}
