摘要：

We report susceptibility experiments in magnetic fields up to 60 T and show conclusively that the de Haas-van Alphen oscillations originate from a single spin Fermi surface. New observed frequencies present in magnetic breakdown and quantum interference oscillations indicate that the Fermi-surface topology changes as a function of the applied field while maintaining a constant volume. These results are not expected from the Anderson lattice model.
