The structural and magnetic properties of two different multilayer systems, Mo/Co and Ag/Co were investigated. The multilayered films were prepared by rf-magnetron sputtering. The saturation magnetization (Ms) of Mo/Co films decreases rapidly with decreasing modulation wave-lengths. Contrary to this result we have observed a slight increase of the Ms of Ag/Co. One of the reasons for the difference in the magnetic properties between two systems can be ascribed to the higher solid solubility of the Mo/Co system compared with Ag/Co. The influence of the substrate temperature and post heat treatment on the interfacial structure and magnetic properties has also been studied. Furthermore, we have measured the magnetization curves, and Kerr rotation angles as a function of modulation length. The magnetic properties are discussed in more detail in relation to the interfacial structures.
