用极化中子反射法测定了Fe/Gd和Fe/Cr两种不同反铁磁耦合多层膜系统的磁结构。在Fe/Gd中，Fe和Gd的力矩在界面处反平行耦合。在Fe/Cr中，当退火温度高达425°C时，Fe层间的反铁磁耦合退化，形成铁磁耦合区。
Polarized neutron reflection was used to determine the magnetic structure of two different antiferromagnetically coupled multilayer systems, Fe/Gd and Fe/Cr. In Fe/Gd, the Fe and Gd moments are coupled antiparallel at the interface. At low temperatures a surface-induced magnetic phase transition was found. In Fe/Cr, annealing at temperatures of up to 425°C resulted in the degrading of antiferromagnetic coupling between Fe layers and in the formation of ferromagnetically coupled regions.
