Abstract

We demonstrate experimentally that a one-dimensional array of silicon nanowires periodically placed on a nickel substrate enhances the transverse magneto-optical Kerr effect (TMOKE) compared to a nickel film. The enhancement mechanism is associated with the excitation of two types of resonances: multipole Mie resonances in each nanowire and surface lattice resonances (SLRs) emerging from the periodic arrangement of the nanowires. The maximal TMOKE values reached up to 1.9 and 2.6% due to the excitation of SLR and a magnetic dipole resonance, respectively. When the SLR is excited, the spectral width of the TMOKE enhancement is narrower compared to the case of the magnetic dipole resonance.

通过米氏共振和表面晶格共振增强硅镍纳米晶中的横向磁光克尔效应

摘要我们通过实验证明，与镍薄膜相比，周期性放置在镍基底上的一维硅纳米线阵列能增强横向磁光克尔效应（TMOKE）。增强机制与两种共振的激发有关：每根纳米线中的多极米氏共振和纳米线周期性排列产生的表面晶格共振（SLR）。由于激发了表面晶格共振和磁偶极共振，TMOKE 的最大值分别达到了 1.9% 和 2.6%。当激发 SLR 时，TMOKE 增强的光谱宽度比磁偶极子共振时要窄。

期刊介绍： The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
