Acting on optical magnetic dipoles opens novel routes to govern light-matter interaction. We demonstrate magnetic field modification of the magnetic dipolar moment characteristic of resonant nanoholes in thin magnetoplasmonic films. This is experimentally shown through the demonstration of the magneto-optical analogue of Babinet's principle, where mirror imaged MO spectral dependencies are obtained for two complementary magnetoplasmonic systems: holes in a perforated metallic layer and a layer of disks on a substrate.
光磁偶极子的作用为控制光与物质相互作用开辟了新途径。我们证明了在薄磁等离子体薄膜中共振纳米孔的磁偶极矩特性的磁场修饰。这通过演示 Babinet 原理的磁光类似物来实验证明，对于两个互补的磁等离子体系统：在穿孔金属层中的孔和在基底上的盘层，获得了镜像成像的 MO 光谱依赖性。
