Description	Antiferromagnetic resonance is observed in the spectra of magnetic permeability below the N´eel temperature TN.An additional weak and heavily-damped excitation is seen in the spectra of complex dielectric permittivity within the same frequency range. This excitation contributes to the dielectric spectra in both antiferromagnetic and paramagnetic phases. A detailed analysis of these results and of previously published magnon dispersion branches brought us to the conclusion that the observed absorption bands stem from phonon-phonon and phonon-paramagnon differential absorption processes.
