N2 - The degenerate semiconductor PbTe with a NaCl-type cubic structure is found to exhibit a huge H-linear magnetoresistance Δρ=ρ in magnetic fields up to the highest applied field of 500 kOe, revealing Δρ=ρ = 270 at 500 kOe, with Shubnikov–de Haas (SdH) oscillations. The present magnetoresistance is due to small nearly ellipsoidal electron Fermi surfaces at the L point in the fcc Brillouin zone. A magnetic field of 350 kOe corresponds to the quantum limit (Landau level l = 0) for the fundamental SdH oscillations, leaving only the lowest down-spin Landau level in higher magnetic fields. We clarified the present Fermi surfaces by a de Haas–van Alphen experiment and relativistic linearized augmented plane wave energy band calculation. Similar results were obtained for PbS with small nearly spherical electron Fermi surfaces.
