Abstract
We investigate yttrium iron garnet (YIG)/cobalt (Co) heterostructures using broadband ferromagnetic resonance (FMR). We observe an efficient excitation of perpendicular standing spin waves (PSSWs) in the YIG layer when the resonance frequencies of the YIG PSSWs and the Co FMR line coincide. Avoided crossings of YIG PSSWs and the Co FMR line are found and modeled using mutual spin pumping and exchange torques. The excitation of PSSWs is suppressed by a thin aluminum oxide interlayer but persists with a copper interlayer, in agreement with the proposed model.
摘要
我们使用宽带铁磁共振（FMR）研究钇铁石榴石（YIG）/钴（Co）异质结构。当 YIG 体层中 PSSW 的共振频率与 Co FMR 线重合时，我们观察到在 YIG 层中垂直驻波自旋波（PSSW）的有效激发。通过自旋泵浦和交换转矩的相互作用，我们发现并对 YIG PSSW 和 Co FMR 线的避免交叉进行了建模。氧化铝中间层虽然会抑制 PSSW 的激发，但铜中间层却可以使其持续存在，这与所提出的模型一致。
