The intrinsic modes localized near domain walls in anisotropic antiferromagnet are studied theoretically. The intrinsic mode frequency dependence on the field was received in the framework of the effective equa-tions for antiferromagnets. The analytical results were compared with the experimental data for hf resonance in quasi-two-dimensional antiferromagnet Mn2P2S6.

PACS: 63.20.Pw Localized modes;
PACS: 76.50.+g Ferromagnetic, antiferromagnetic and ferrimagnetic resonances.

Key words: antiferromagnets, AFM resonance, domain wall, localized modes.
