已经观察到的反铁磁耦合的强度的依赖关系的Co层厚度上的Cu。Co厚度依赖性显示了两个清晰的峰值，与最近预测的6.2 A Co的振荡周期一致。除了这两个峰值外，在约1个单层Co的尺度上还可以看到几个小峰值。自由电子计算表明，强度的这些快速变化可能是由于实验中涉及的两个Co楔形的斜率和起始点之间的微小差异造成的。
A dependence of the strength of the antiferromagnetic coupling across Cu on the Co layer thickness has been observed. The Co thickness dependence displays two clear peaks consistent with the recently predicted oscillation period of 6.2 A Co. Apart from the two peaks also several small peaks are visible on a scale of about 1 monolayer Co. Free‐electron calculations indicate that these rapid variations in strength may result from slight differences between the slopes and starting points of the two Co wedges that were involved in the experiment.
