- We present the results of the low temperature electron paramagnetic resonance (EPR) and transport investigations of the crystals of Pb$\text{}_{1-x}$Cr$\text{}_{x}$Te (x ≤ 0.01). The samples with chromium concentrations x ≥ 0.0015 are all n-type. For these samples we observe the single EPR line with the g-factor decreasing from g = 1.97 till g = 1.93 with increasing carrier concentration. This resonance can be attributed to electrically and magnetically active Cr$\text{}^{3+}$ ions. The crystals with Cr concentration x ≤ 0.0015 may be both n- and p-type. The EPR spectrum of these samples consists of two lines: the one discussed above and the other one with g = 1.99 observed only for samples with electron concentration n ≤ 10$\text{}^{18}$ cm$\text{}^{-3}$.
