| Hall effect, conductivity, electron paramagnetic resonance and magnetization of Pb1-xCrxSe (x ≤ 0.01) crystals were measured as a function of Cr content and electron concentration. The experimental results suggest that Cr in PbSe creates a resonant donor state with the energy of about 125 meV above the bottom of the conduction band. |
