论文摘要
在这项工作中，证明了将材料与铁磁和等离子特性相结合的2D磁性光栅结构。 Nife复合铁磁材料是具有可调物理特性的活性培养基，而Au Metal（作为等离子体激发层）是选择的材料。在这里，我们通过外部磁场的作用以及系统的开关效应，通过实验研究了AU/Nife BiLayer中等离子体特性的主动控制。活跃的等离子体控制可以通过铁磁材料的磁化切换来实现，从而为活性等离子体设备开发开发了新的路径。据我们所知，这是基于等离子与磁光活性材料的偶联的磁光光震动开关的首次演示，其中估计响应时间在微秒范围内。
In this work, a 2D magneto-plasmonic grating structure combining materials with ferromagnetic and plasmonic properties is demonstrated. NiFe composite ferromagnetic material, as an active medium with tunable physical properties, and Au metal, as a plasmonic excitation layer, were the materials of choice. Here, we have experimentally investigated the active control of the plasmonic characteristics in Au/NiFe bilayer by the action of an external magnetic field, as well as the switching effect of the system. The active plasmonic control, can be achieved by the magnetization switching of the ferromagnetic material, opening a new path in the development of active plasmonic devices. To our best knowledge, this is the first demonstration of such a magneto-optical plasmonic switch based on the coupling of plasmons with magneto-optical active materials, in which the response time was estimated to be in the range of microseconds.
