Comment on 'Magnetic phase transition in Co/Cu/Ni/Cu(100) and Co/Fe/Ni/Cu(100)'

摘要

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 donot object the presented results, we remark that published work was notcommented on. Especially, much more information can be extracted out of themeasurements by a quantitative comparison with an appropriate model, allowingfor a determination of important parameters such as exchange couplingconstants.
