A detailed investigation of the composition dependences of magnetoresistance for polycrystalline Bi₁₋ₓSbₓ solid solutions in a concentration range x = 0 – 0.07 was performed at 300 K in weak and strong magnetic field. It was shown that the composition dependences of magnetoresistance are clearly expressed nonmonotonic type. The presence of concentration anomalies of magnetoresistance was confirmed that had been earlier observed in the range x = 0 – 0.1 on cast samples after different kinds of thermal treatment and interpreted as a manifestation of electron phase transitions. It is shown that the position of the extrema does not depend on the magnitude of the magnetic field in the interval 0.01 - 1.0 T.
