We investigate how the static and dynamical magnetic properties of Fe/Cr finite superlattices with antiferromagnetic coupling depend on the ratio between the uniaxial anisotropy constant and the interlayer exchange constant of Fe films. The spin waves are calculated by considering dipole interaction, intralayer and interlayer exchange coupling, uniaxial anisotropy, in presence of an external field. The calculated spectra are compared with recent experimental Brillouin scattering data which exhibit two spin waves peaks.
