A study of the de Haas-van Alphen oscillations in the magnetic susceptibllity was carried out in p-type PbTe and --n-type PbS. Measurements were made on oriented single crystal samples with carrier concentrations of the order of 10¹⁸ cm³ in pulsed magnetic fields up to 125 kgauss. The results for p-type PbTe indicate that the valence bands have a maximum at k = 0, and four equivalent maxima at the (111) Brillouin zone faces. The (111) ellipsoids have a longitudinal mass to transverse mass ratio of 6.4 plus or minus 0.3. From the temperature dependence of the amplitude of the oscillations a value of 0.043 plus or minus 0.006 m₀ for the transverse effective mass was obtained. The data indicate that the (000) maximum and the (111) maxima lie within 0.002 plus or minus 0.002 ev of each other. The data also indicate an effective broadening temperature of about 8 deg K which is attributed to inhomogeneities in the carrier concentrations in the samples investigated. Preliminary results on n-type PbS show a single isotropic Fermi surface cross section with a cyclotron mass of 0.14 plus or minus 0.04 m/sub 0/. The direct and indirect optical interband transitions are discussed in the light of these results. (auth)
