摘要

近年来，磁振子晶体作为光子晶体或声子晶体的磁性对应物逐渐成为研究的热点。本文提出了一种在磁晶体领域中的平面波展开方法。用该方法计算了由铁磁材料Fe和EuO组成的二维磁子晶体的能带结构。数值结果表明，在一定的填充分数比下会产生自旋波隙，且有效场中交换场对能带结构的影响大于其他场。

Band-structure calculations of two-dimesional magnonic crystals with plane-wave expansion method*

Recently, magnonic crystals which are the magnetic counterparts of photonic crystals or phononic crystals are growing into a hot area of research. In this paper, a plane-wave expansion method in the field of magnonic crystals is proposed. By using this method, band structures of two-dimensional magnonic crystals composed of ferromagnetic materials Fe and EuO are calculated. The numerical results show that the spin-wave gaps will be generated under a definite filling fraction ratio, and the effect of exchange field on the band structure is larger than that of other field in the effective field.
