We demonstrate a perspective approach for the fabrication of functional high-quality magnetoplasmonic crystals based on a 2D periodical perforated silver film covered by a thin layer of ferromagnetic metal (Permalloy). The wavelength-angular spectra of the 2D crystals reveal a large number of high-quality resonant features associated with the excitation of surface plasmon-polariton modes of various orders. Due to the presence of a ferromagnetic material on both plasmonic interfaces, pronounced magnetic effects are observed for all excitations and are influenced by the coupling between various modes. The suggested magnetoplasmonic crystal composition with high-quality resonant optical and magneto-optical properties gives perspective for the control over the light propagation as well as for sensor applications.We demonstrate a perspective approach for the fabrication of functional high-quality magnetoplasmonic crystals based on a 2D periodical perforated silver film covered by a thin layer of ferromagnetic metal (Permalloy).

二维高质量 Ag/Py 磁等离子体晶体

我们展示了一种基于由铁磁金属（坡莫合金）薄层覆盖的 2D 周期性穿孔银膜制造功能性高质量磁等离子体晶体的透视方法。二维晶体的波长-角光谱揭示了大量与不同阶表面等离子体-极化子模式激发相关的高质量共振特征。由于在两个等离子体界面上都存在铁磁材料，因此所有激发都会观察到明显的磁效应，并且受到各种模式之间耦合的影响。建议的具有高质量共振光学和磁光特性的磁等离子体晶体成分为控制光传播以及传感器应用提供了前景。我们展示了一种基于由铁磁金属（坡莫合金）薄层覆盖的 2D 周期性穿孔银膜制造功能性高质量磁等离子体晶体的透视方法。二维晶体的波长-角光谱揭示了大量与不同阶表面等离子体-极化子模式激发相关的高质量共振特征。由于在两个等离子体界面上都存在铁磁材料，因此所有激发都会观察到明显的磁效应，并且受到各种模式之间耦合的影响。建议的具有高质量共振光学和磁光特性的磁等离子体晶体成分为控制光传播以及传感器应用提供了前景。
