The increasing demand for thin-layer materials influences on development of their production technologies and a range of potential applications. The properties of these materials (e.g. physical properties) can find new applications and solve existing limitations. Multi- and thin-layer metal systems are a special group of materials which can be successfully used for suppression of electromagnetic waves. Properly designed multilayer systems can exhibit the effect of a giant magnetoresistance. The research results include morphology observations and study of surface topography of Cu/Ni multilayer systems with nanometric layers. The layers were electrolytically produced on a thin copper foil substrate. The investigations of the physical properties of the systems have shown that quantity and thickness of the layers in the multilayer system have an effect on magnetic properties. The obtained layers are characterized by good quality. Moreover, they are compact and homogeneous. The topographical studies have not detected major surface defects of multilayer systems.
