A system of three magnetic (M) layers divided by nonmagnetic (N) spacers is considered. The existence of roughness on the interfaces, described by the model proposed by Bruno and Chappert, leads to a modification of interlayer exchange coupling (IEC). The Curie temperature and magnetisation are calculated using the Green function formalism for the system of layers with Fe standing for M and Cu or Au standing for N. The parameters characterising this system are taken into account for the GaAs substrate. The results obtained show a decreasing Curie temperature with the increasing roughness parameter as compared to the Curie temperature of the sample with an ideal interface. The magnetisation curves are shifted as a result of roughness in the interface region.
