Abstract The galvanomagnetic properties of single crystals of the diluted magnetic semiconductor Hg1−x MnxTe1−y Sey (0.01〈y〈0.1) with x=0.05 and 0.14 have been investigated in the temperature range 4.2–300 K. Peculiarities of the temperature dependence of the Hall coefficient R H and its complicated behavior in a magnetic field are quantitatively explained by the existence of three groups of current carriers: electrons and two types of holes with different mobilities for which the temperature dependence of concentration and mobility was obtained. A transition from p-type to n-type conductivity was observed with increase of Se content, alongside with a simultaneous change of sign of the magnetoresistance from negative to positive.
