Abstract / Description:Shubnikov-de Haas (SdH) and Hall-effect measurements of CeBiPt
and LaBiPt reveal the presence of very small Fermi surfaces
with hole-like charge carriers for both semimetals. Reasonable
agreement with band structure calculations is achieved when
taking spin-orbit coupling into account and assuming localized
Cc 4f electrons. For CeBiPt, we observe a strong temperature
dependence of the SdH frequency, i.e., an increase from similar
to 35 T at 10 K to similar to 60 T at 0.4K, indicating a
possible hybridization of the f electrons.
