We report measurements of the Hall effect and the transverse magnetoresistance of n- and p-type PbTe with carrier concentrations as low as 1.8×1016 cm−3 in magnetic fields up to 15 T. The data rule out the existence of deep impurity levels and are, however, not in contradiction with the presence of resonant levels due to Pb or Te vacancies within the bands according to the model by Parada and Pratt.
