实验研究了一种基于钇铁石榴石（YIG）薄膜的带槽天线的平面自旋波延迟线。所提出的器件的一个具体特征是相对较大（约1.8 GHz）的微波带宽。在该频带内，信号延迟时间可以平滑地控制在4 ~ 18ns之间。中心频率可以通过外磁场在5 - 9ghz范围内调谐。结果表明，采用缝隙天线和较厚的铁磁薄膜，可以显著提高自旋波器件的微波带宽。
A planar spin-wave delay line with slot antennas based on an yttrium iron garnet (YIG) film has been experimentally studied. A specific feature of the proposed device is a relatively large (about 1.8 GHz) microwave bandwidth. Within this band, the signal delay time can be smoothly controlled from 4 to 18 ns. The central frequency can be tuned by an external magnetic field within 5–9 GHz. It is demonstrated that, using slot antennas and relatively thick ferromagnetic films, it is possible to achieve a significant increase in the microwave bandwidth of spin-wave devices.
