Based on the investigation of Ni\/Cu and Cu\/Ni systems with different thickness of magnetic and non\-magnetic layers it was proved that the presence of ferromagnetic \(F\-F\) and antiferromagnetic \(A\-F\) exchange couplings depends on the quality of layers in artificial superlattice and on the state and type of free surface, superlattice structure and its roughness."]
