So far, only basic magnetic and transport properties of Mn2CoSb Heusler alloy have been reported in the literature. In this work, we investigated magnetotransport properties of melt-spun ribbons of Mn2CoSb. The calculation of normal Hall coefficients R_0 revealed a dominant role of electrons in electrical transport of the alloy at temperatures below 200 K. At room temperature, the hole-like conductivity predominates. The dependence of the anomalous Hall coefficient R_S on electrical resistivity ρ _xx , R_S∼ ρ _xx^2 , points to the mechanism of the anomalous Hall effect, independent of the concentration of the scatterers. Pronounced hysteretic features of magnetoresistivity δ ρ _xx were observed upon application and removal of the magnetic field at temperatures below 100 K. It was suggested that the observed hysteresis of δ ρ _xx is related to a magnetic aftereffect in the region of randomly frozen spin states.
