The galvanomagnetic effects, the temperature and magnetic field dependences of mag- netization and electron paramagnetic resonance (EPR) in the Pb1-xVxTe (x ≤ 0.02) alloys under variation of the alloy composition have been investigated. Low temperature activation range of the impurity conductivity on the temperature dependences of the resistivity and the Hall coefficient has been revealed and attributed to the appearance of vanadium-induced deep level in the gap of the alloys. The magnetic susceptibility was found to be a superposition of the matrix diamagnetism and Curie-Weiss paramagnetism provided by vanadium impurity ions. EPR spectra were measured and the g-factor in the temperature range 85-200 K was obtained.
