通过在钇铁石榴石薄膜表面蚀刻浅槽光栅实现一维磁力晶体的反向体积静磁自旋波的散射，进行了实验研究。清晰地观察到抑制频带。抑制效率和抑制带的频率宽度随着凹槽深度的增加而增加。基于自旋波薄膜波导与微波传输线类比的理论模型被用来解释所获得的实验结果。 (C) 2008 年美国物理研究所。
Scattering of backward volume magnetostatic spin waves from a one-dimensional magnonic crystal, realized by a grating of shallow grooves etched into the surface of an yttrium iron garnet film, was experimentally studied. Rejection frequency bands were clearly observed. The rejection efficiency and the frequency width of the rejection bands increase with increasing groove depth. A theoretical model based on the analogy of a spin-wave film waveguide with a microwave transmission line was used to interpret the obtained experimental results.
