Dependence of the interlayer exchange coupling on the constitution of the magnetic layers

This is the authors' abstract. We don't add key points for this paper.

We describe the consequences on the interlayer exchange coupling by the addition of a small amount of Ag impurities within the Co layers of high crystalline quality Co/Cu/Co(Ag) and Cu/Ru/Co(Ag) trilayers, while maintaining the integrity of the spacer layers. We discuss the consequent changes in the amplitude, period, and phase of the coupling in terms of the modification of interfacial spin-dependent potentials.
