Hall constant, conductivity and magnetic susceptibility of Pb_{1-x-y}Sn_{y}Mn_{x}Te semimagnetic semiconductor were investigated as a func­tion of Mn content (x = 0.04, 0.09, 0.16, y = (0.7-0.8)) in the temperature range T = (4 - 300) K. A ferromagnetic phase transition takes place at T = 5 K for samples with x = 0.04, at T = 10 K for x = 0.09 and at T = 20 K for x = 0.16. For crystals with x ≥ 0.09 the strong temper­ature dependence of the Hall constant is observed for temperatures below 40 K. Magnetic field characteristics of the Hall effect is strongly non-linear at T = 4.2 K. No significant temperature or magnetic field dependence of con­ductivity is observed in the whole temperature range studied. The observed transport anomalies are due to the anomalous Hall effect.
