Abstract

Magnetoresistance, Hall effect, and susceptibility have been investigated in Te-doped Bi₉₅Sb₃ single crystals. The experimental results establish the occurrence of both longitudinal and transversal SdH-oscillations over a wide temperature range up to T = 77 °K. Dingle-temperatures, cyclotron masses, spin splitting, and the effective mass tensor of the electrons at the Fermi level and the band edge were calculated from the temperature and angular dependence of the SdH-oscillations. The results are discussed in respect of various models of the electron band structure. The behaviour of the small Fermi surface cross sections is in agreement with the ENP-model, however in the long direction of the quasi ellipsoids a slight variation of the effective mass must be assumed.
