| The spin-wave resonance in the thin FeBr2 field-induced metamagnet in the paramagnetic phase with the (001) surfaces and at low temperatures is examined theoretically. It is found that the absorption spectrum is strongly affected by modifications of the surface exchange parameters. Also, the conditions for the appearance of various surface and bulk spin-wave features are discussed. |
