## Abstract The dependences of the Hall coefficient __R__~H~ and magnetoresistance Ξ__Ο__ /__Ο__ on magnetic field (__B__ = 0.01β1.0 T) for polycrystalline BiβSb solid solutions with various Sb concentrations (0β15 at% Sb) were obtained at 77 K and 300 K. On the basis of the __R__~H~(__B__) and Ξ__
Electrical resistivity studies have been carried out on three different Bi-Sb alloys in the temperature range 100-300K. The observed behaviour of all the samples, in which one is semimetallic and other two are semiconductors, can be explained on the basis of the model presented for Bi-Sb energy band
