The fermi surface in white tin

Abstract

The orientation dependence of the de Haas-van Alphen periods in tin single crystals has been studied in high pulsed magnetic fields. As many as seven periods have been found at some orientations, indicating that the Fermi surface is much more complicated than the 3-ellipsoid model suggested by Fawcett. The general degree of complexity of the results is much the same as that predicted by the free-electron model, but serious discrepancies are found when a detailed comparison is made. Effective mass values have been determined at the principal orientations from the temperature dependence of the amplitudes; these are compared with the results of cyclotron resonance experiments and with the free-electron orbit masses.
