提出了层间交换耦合理论。对这个问题的各个方面进行了详细而全面的讨论。层间交换耦合是用超薄层中由于约束而产生的量子干涉来描述的。这种方法既提供了耦合机制的物理透明图像，又为讨论实际系统的情况提供了合适的方案。这是对Co/Cu/Co（001）体系的说明。通过引入复费米曲面的概念，统一处理了金属间隔层和绝缘间隔层的情况。
A theory of interlayer exchange coupling is presented. A detailed and comprehensive discussion of the various aspects of the problem is given. The interlayer exchange coupling is described in terms of quantum interferences due to confinement in ultrathin layers. This approach provides both a physically transparent picture of the coupling mechanism, and a suitable scheme for discussing the case of a realistic system. This is illustrated for the Co/Cu/Co (001) system. The cases of metallic and insulating spacers are treated in a unified manner by introducing the concept of the complex Fermi surface.
