Observation of Heavy Hole State in CeSb

抄録

The acoustic de Haas van Alphen effect of the low carrier compound CeSb has been measured by a homemade dilution refrigerator. The heavy hole orbit of β₄ in the ferromagnetic phase has been clearly observed. The cyclotron effective mass of β₄ under the magnetic field along [001] direction was 4.3m₀. The angular dependence of the cross-sectional area of β₄ is well explained by the band calculation based on the p-f mixing model. Some aspects of the electron-strain interaction obtained by the oscillation intensity of the elastic constant are discussed.
