| Sumario: | Westudyrigid displacementexcitations ofa Nèelwallof a thin uniaxial ferromagnetic film on a two-sublattice antiferro-magnetic substrate. An interface step defect pins the domain walland provides the restoring force that stabilizes the domain walloscillations. The frequency of the rigid displacement domain wallmodes is shown to be of the same order of magnitude as that of theuniform domain modes of the ferromagnetic film, for a wide rangeof interface exchange energy values. |
