Magnetic and galvanomagnetic properties of the group II-V semiconductor CdSb single crystals doped with Ni are reported. The magnetization data give evidence for spheroidal Ni- rich Ni1-xSbx nanoclusters. Mechanism of the low-temperature conductivity is sensitive to the magnetic field, being of the variable-range hopping type in zero field and of the nearest- neighbor hopping type in strong fields. The Hall resistivity contains the normal and the anomalous contributions.
