金属多层膜中的层间耦合通常被认为与通过传导电子的磁矩的RKKY耦合无关。通过分析铁基体上铬自旋极化的最新实验数据，我们证实 RKKY 耦合本身无法解释 Fe/Cr 多层膜中的层间耦合。数据保证了额外的耦合，我们解释了它的起源
Interlayer coupling in metallic multilayers is generally thought to be alun tothe RKKY coupling of magnetic moments through conduction electrons. By analysing recent experimental data on the spin polarisation of chromium on iron substrates we confirm that the RKKY coupling cannot by itself explain the interlayer coupling in Fe/Cr multilayers. An additional coupling is warranted by the data, and we explain its origin
