Abstract
A step defect at the interface between a two – sublattice antiferromagnetic substrate and a uniaxial ferromagnetic thin film stabilizes a Nèel wall. Breathing domain wall modes (BDWM) are studied with the external field in the plane of the film. 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 significant 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 effective exchange field and the anisotropy field of the ferromagnetic film.
