Enhanced analysis can improve understanding of magnetic interactions.

Abstract

In a recent Letter the phase diagram of Co/Cu/Ni/Cu(100) and Co/Fe/Ni/Cu(100) trilayers was determined experimentally as well as theoretically. Whereas we do not object the presented results, we remark that published work was not commented on. Especially, much more information can be extracted out of the measurements by a quantitative comparison with an appropriate model, allowing for a determination of important parameters such as exchange coupling constants.
