We unravel the underlying near-field mechanism of the enhancement of the magneto-optical activity of bismuth-substituted yttrium iron garnet films (Bi:YIG) loaded with gold nanoparticles. The experimental results show that the embedded gold nanoparticles lead to a broadband enhancement of the magneto-optical activity with respect to the activity of the bare Bi:YIG films. Full vectorial near- and far-field simulations demonstrate that this broadband enhancement is the result of a magneto-optically enabled cross-talking of orthogonal localized plasmon resonances. Our results pave the way to the on-demand design of the magneto-optical properties of hybrid magneto-plasmonic circuitry.

混合金负载Bi：YIG增强宽带磁光活性的近场机理

我们揭示了负载金纳米颗粒的铋取代钇铁石榴石薄膜（Bi：YIG）的磁光活性增强的潜在近场机制。实验结果表明，相对于裸Bi：YIG膜的活性，包埋的金纳米颗粒导致磁光活性的宽带增强。完全矢量近场和远场仿真表明，这种宽带增强是正交局部等离振子共振的磁光启用串扰的结果。我们的结果为混合磁等离子体电路的磁光特性的按需设计铺平了道路。
