Abstract
The electronic states that mediate the interlayer exchange coupling and the corresponding coupling strengths are calculated for Co/Cu(100). It is found that some states are strongly confined within the spacer layer. This is shown to lead to a strong RKKY-like coupling, but also to some weak contributions from higher harmonics. Weaker confined states only contribute by a rather weak RKKY coupling.
