中文摘要：
近年来，对磁振子晶体的研究已成为热点，与光子晶体等复合材料的性质类似，磁振子晶体也有带隙现象出现，频率在带隙范围内的自旋波在磁振子晶体内将被禁止传播。由此磁振子晶体有望能够被应用于广泛的仪器制造中。本文采用平面波展开法数值计算了分别由铁与钴、铁与氧化铀、钴与氧化铀材料构成的一维无限大各向同性的磁振子晶体的带结构，讨论了不同的填充率对磁振子晶体带隙结构的影响。计算结果表明，交换作用场对自旋波带宽的影响很明显。
英文摘要：
Recently,the study of magnonic crystals has been growing intensively as a new research field. Magnonic crystal with frequency gaps in which spin-wave excitations are forbidden from propagating particularly like photonic crystals. So the magnonic crystal can he applied hopefully and extensively onto instrument manufacturing. By using proposed plane-wave expansion method, band structures of one-dimensional magnonie crystals composed by ferromagnetic homogeneous materials are calculated. The numerical results show that spin-wave gaps will be generated under the definite range of filling fraction rations, and the effect of exchange field is evident to the band gaps.
