Abstract
We report susceptibility experiments in magnetic fields up to 60thinspthinspT and show conclusively that the de Haas{endash}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. {copyright} {ital 1998} {ital The American Physical Society}

Title Quantum interference in the spin-polarized heavy fermion compound CeB6: Evidence for topological deformation of the fermi surface in strong magnetic fields
In this Letter, we report the results of extending quantum interference (QI) and magnetic breakdown (MB) measurements to CeB6, which is known to have a Fermi surface (FS) similar to LaB6 [5]
We find that in several respects, the behavior of the de Haas–van Alphen (dHvA) oscillations is consistent with the theory for the dHvA effect in heavy fermion (HF) systems developed by Wasserman et al [8]
