讨论了层状磁性结构中的自旋波模。文中给出了用光散射方法获得的实验实例。重点讨论了磁性双层中的耦合模，即由非铁磁中间层隔开的两个铁磁性薄膜。耦合可以通过处理自旋引起的振荡偶极场，或者通过交换相互作用。它展示了如何使用耦合模式来探索这种相互作用。这些研究导致了层间交换作用的发现。
The spinwave modes occurring in layered magnetic structures are discussed. Experimental examples obtained by means of light scattering are presented. Emphasis is put on coupled modes occurring in magnetic double layers, i.e. two ferromagnetic films, separated by a nonferromagnetic interlayer. The coupling can be via oscillating dipolar fields caused by the preccessing spins, or via the exchange interaction. It is shown, how the coupled modes can be used, to explore such interactions. These investigations have led to the discovery of the interlayer exchange interaction.
