75.70.-i - Opis:
- 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$\text{}_{x}$Au$\text{}_{1-x}$ 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$\text{}_{x}$Au$\text{}_{1-x}$ 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.
