Magnetotransport, including the magnetoresistance (MR) and the Hall effect, isinvestigated in polycrystalline In1-xMnxSb samples with x = 0.02 – 0.06, containing nanosize MnSb precipitates. The relative MR, Δρ/ρ, is positive within the whole range of B= 0 – 10 T and T ~ 20 – 300 K. The Hall resistivity, ρH, exhibits a nonlinear dependence on B up to the room temperature.MR is interpreted with the two-band model, suggesting two types of holes with different concentration and mobility. In addition, analysis of ρH (B, T) is performed by taking into account both the normal and the anomalous contributions. The latter is attributable to the effect of MnSb nanoprecipitates, having the ferromagnetic Curie temperature well above 300 K.
