Engineering antiferromagnetic magnon bands through interlayer spin pumping
Synthetic antiferromagnets are tunable metamaterials that offer a fertile platform for investigating interactions between optical and acoustic magnons, which can be exploited to engineer the magnon energy spectrum. This study examines how dynamic interlayer spin pumping within synthetic antiferromagnets can hybridize acoustic and optical magnons. To interpret the experimental results, the Landau-Lifshitz-Gilbert theory is extended to describe the fieldlike and dampinglike torques in a generic noncollinear magnetic multilayer. These findings provide the hybrid-magnonics community with a fresh approach to engineering and modeling magnon-magnon interactions in antiferromagnets.
