Abstract

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.
