对于mbe生长Au/Fe/Au/Fe/Au（001）薄膜，研究了跨Au间隔层间交换耦合对Fe层厚度的依赖关系，该薄膜包含两个阶梯状的Fe层，每一级高1ml。耦合强度随各Fe层厚度的变化而振荡，振荡周期为2 ML，这是由于涉及铁多数自旋带的共振态。研究了Fe/Si和Fe/FeSi多层膜层间耦合随半导体间隔层厚度和温度的变化规律。
Fe layer thickness dependence of the interlayer exchange coupling across a Au spacer is investigated for MBE-growth Au/Fe/Au/Fe/Au(001) films involving two step-shaped Fe layers with each step 1 ML high. The coupling strength oscillates as a function of each Fe layer thickness with a 2 ML Fe period, which is attributed to the resonance state involving the Fe majority spin band. The interlayer coupling is also studied for Fe/Si and Fe/FeSi multilayers as functions of semiconducting spacer thickness and temperature.
