The results of various experiments on interlayer exchange coupling will be reviewed. After a general discussion of the theoretical understanding we deal first with 90°-type coupling and show that two mechanisms proposed by Slonczewski can explain our measured data. We furthermore study the coupling of Fe films across Cu_{x}Au_{1-x} alloys. For the composition with x=0.5, the coupling strength strongly increases with annealing. We believe that this is due to an order-disorder structural transformation in the Cu_{x}Au_{1-x} alloy. Finally, we present results on epitaxially grown bilayers Fe/EuS(100) and trilayers Fe/EuS/Fe(100). In the latter at room temperature we observe a strong decrease in the coupling strength as a function of the interlayer thickness, with a characteristic length of about 0.1 nm. At low temperatures in the bilayer we find an antiferromagnetic coupling between Fe and the adjacent ferromagnetic EuS.
