摘要

布里渊光散射(BLS)光谱是探测磁性薄膜和纳米结构中自旋波的有力工具。尽管可以全面获得自旋波特性,但BLS光谱学受到可探测自旋波波数有限和通常相对较低灵敏度的影响。在本文中,我们给出了基于最近发展的描述等离子体增强BLS的解析模型的数值模拟结果。有效磁化率定义为旋转椭球形状的单个等离子体纳米粒子,由介电间隔分隔的夹在一起的等离子体纳米粒子,以及磁膜表面的等离子体谐振器阵列。结果表明,金属纳米粒子的偏心率,描述了它们的形状,在增强BLS信号中起主导作用。对不同能量光子的金、银等离激元系统,用数值方法确定了BLS增强的最佳条件。本文的研究结果为等离子体增强BLS光谱的实验实现指明了方向。2025年由美国物理学会出版

Plasmon-enhanced Brillouin light scattering spectroscopy for magnetic systems. II. Numerical simulations
Brillouin light scattering (BLS) spectroscopy is a powerful tool for detecting spin waves in magnetic thin films and nanostructures. Despite comprehensive access to spin-wave properties, BLS spectroscopy suffers from the limited wave number of detectable spin waves and the typically relatively low sensitivity. In this paper, we present the results of numerical simulations based on the recently developed analytical model describing plasmon-enhanced BLS. Effective susceptibility is defined for a single plasmonic nanoparticle in the shape of an ellipsoid of rotation, for the sandwiched plasmonic nanoparticles separated by a dielectric spacer, as well as for the array of plasmonic resonators on the surface of a magnetic film. It is shown that the eccentricity of the metal nanoparticles, describing their shape, plays a leading role in enhancing the BLS signal. The optimal conditions for BLS enhancement are numerically defined for gold and silver plasmon systems for photons of different energies. The presented results define the roadmap for the experimental realization of plasmon-enhanced BLS spectroscopy. Published by the American Physical Society 2025
