Abstract
The anisotropic diamagnetic susceptibility of free holes in pure and antimony-doped tellurium single crystals has been determined in the temperature range from 5 to 300 °K. The susceptibility %L depends on the hole concentration p as %L ∼ p1/3, for concentrations above 1017 cm-3 , according to the behaviour of a degenerate electron gas in a parabolic band. The magnitude of the susceptibility is in principle determined by the band parameters connected with the relevant spin-split hole states. As an approximation, the Pauli-Landau-Peierls formula has been used with the values of the effective mass tensor as known from magnetoabsorption, cyclotron resonance and Shubnikow-De Haas results (m⊥ = 0,11 m, mⅡ = 0,26 m). Effective g-values g⊥ = 3,5 ± 0,7 and gⅡ = 9,6 ± 0,5 were found. The large deviation from two indicates that the hole states are heavily influenced by spin-orbit interaction.Keywords
