Description:
Author(s): E. Mun, S. L. Bud'ko, Y. Lee, C. Martin, M. A. Tanatar, R. Prozorov, and P. C. Canfield Heavy fermion systems are useful for studying quantum criticality because the low energy scale associated with their large effective mass can be tuned by nonthermal control parameters. Here, Shubnikov-de Haas oscillations are observed in YbPtBi, a heavy fermion compound with an exceptionally large effective mass for electrons, at a high magnetic field that reveals the shape of the Fermi surface. In the future these observations, when combined with additional data at lower magnetic fields, could provide important information about quantum criticality in these systems. [Phys. Rev.
