摘要:

实验研究了在钇铁石榴石薄膜表面刻蚀浅槽光栅实现的后向体静磁自旋波在一维磁振子晶体中的散射。清晰地观察到抑制频带。随着槽深的增加,抑制效率和频带宽度增加。基于自旋波薄膜波导与微波传输线的类比的理论模型被用来解释所获得的实验结果。

英文摘要:

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.
