Galvanomagnetic Effects and Magnetic Susceptibility of Tin-Doped Bismuth Crystals

In order to obtain the detailed information on the valence band of bismuth crystals, the low-field galvanomagnetic tensor components of 0.2 atomic percent tin-doped bismuth single crystals were measured at 77°K together with the angular dependence. The results are interpreted in terms of one heavy-hole and three light-hole ellipsoid model. The values of the mobility tensor determined from the model are in fairly good agreement with experiments, and the tilt angle for the light-hole ellipsoid is estimated to be about 15°. The temperature variations of the resistivity, Hall coefficient and magnetic susceptibility were also measured, and the discussions based on the present model are made.
