Abstract: Relatively large n-type Pb1-x Sn x Te single crystals with various x values (x=0–0.28) were prepared and the Shubnikov-de Haas oscillations were measured. The results indicate that the Fermi surface consists of four [111] spheroids whose anisotropies increase with decreasing band gap. The effective mass and effective g *-values of the conduction band were estimated as functions of the alloy composition, and the results are analyzed by a simple two-band non-parabolic model, which gives the transverse momentum matrix element P ⊥=√0.58(1+0.211x)/2, and the longitudinal momentum matrix element P //=√0.046(1-0.142x)/2, both in atomic units (a.u.).
