Query: Anomalous temperature dependence of magnetic quantum oscillations in
  CeBiPt   Shubnikov--de Haas (SdH) and Hall-effect measurements of CeBiPt and LaBiPt
reveal the presence of simple and very small Fermi surfaces with hole-like
charge carriers for both semimetals. In the magnetic material, CeBiPt, we
observe a strong temperature dependence of the SdH frequency. This highly
unusual effect might be connected with an internal exchange field within the
material and a strongly spin-dependent scattering of the charge carriers.
