摘要：

The spin-wave spectrum of a thin ferromagnetic film in presence of dipolar interactions and single-ion anisotropy is calculated within a Green's function approach. In the continuum limit, analytical results are obtained for the frequency of the acoustic model of the multilayer, which allow to follow the transition, with decreasing wavevector, from the microscopic approach to the regime of magnetostatic modes.
