Abstracts

EN

The EPR studies of CdTe:Cr were performed on X-band (9.6 GHz) spectrometer at room temperature. Single CdTe crystals were doped by chromium Cr in the synthesis process. The spectra observed were resolved into two spectra. The first one consisted of very broad line (Δ B=100 mT) and the second one showed a typical fine structure. The complete angular dependence measurements were obtained. The fine structure of Cr^{2+} or Cr^{3+} ions was assumed and simulated. It follows from the theoretical analysis of the obtained spectra that degree of ionization of the chromium Cr dopant is 3+.
