摘要：

We investigate how the spin waves spectra of Fe/Cr finite superlattices with antiferromagnetic coupling depend on the interface anisotropy (in-plane and out-of-plane). The magnetic ground state, evaluated within the mean field approach, exhibits a canted configuration of the static magnetization. The spin waves are calculated by considering dipole interaction, intralayer and interlayer exchange coupling, uniaxial and interface anisotropies, in presence of an external field. The calculated spectra are compared with recent experimental Brillouin scattering data which show two spin waves peaks.
