dc.description.resumo	Astep defect at the interface between a two } sublattice antiferromagnetic substrate and a uniaxial ferromagnetic thin "lm stabilizes a Ne`el wall. Breathing domain wall modes (BDWM) are studied with the external "eld in the plane of the "lm. The restoring force of the domain wall excitations originates from the interface exchange energy within the domain wall. For low anisotropy ferromagnets there is a signi"cant reduction of the domain wall width and the frequency of the domain wall excitations is determined from the interface exchange coupling in a small interface area. For strong interface coupling, the width of the domain wall excitation spectrum scales with the square root of the ratio between the interface e!ective exchange "eld and the anisotropy "eld of the ferromagnetic "lm. 2001 Elsevier Science B.V.
