中文摘要：

使用等效介质理论研究了在Voigt位形下，由反铁磁半导体和绝缘非磁物质构成的半无限侧向反铁磁／非磁超晶格中的表面推迟模。讨论了在外磁场为零和非零两种情况下涡流对推迟模的影响，给出了同时考虑传导电流和位移电流时，侧向反铁磁／非磁超晶格的频率与波矢的关系曲线以及自旋波衰减随波矢k的变化曲线。

英文摘要：

Using the equivalent medium theory, we have investigate the surface retarded modes of a semi-infinite lateral superlattices composed of semiconductor antiferromagnetic layers and insulating nonmagnetic layers in the Voigt geometry. We studied the effect of eddy current on surface retarded modes of a lateral antiferromagnetic/nonmagnetic superlattice when the external field is zero or nonzero. Particularly, we have considered the effect of conduction current and displacement current on the retarded modes, and have obtained for the first time the curves for different cases of the frequency and the spin wave damping versus the wave vector k.
