| Abstract: | The temperature dependence of the Cr2O3 EPR spectra is obtained. The linewidth of the EPR is defined by the phonon's modulation of the exchange interactions at T >TN + 4–5 K though at TN < T < TN + 4 K the critical broadening of the EPR in Cr2O3 is determined by fluctuation effects. |
