Magneto-Plasmonic Properties of Au/Fe/Au Planar Nanostructures: Theory and Experiments

Publication date: 2016 Source:Procedia Materials Science, Volume 12 Author(s): Jaroslav Vlček, Michal Lesňák, Petr Otipka, Jaroslav Sobota The non-reciprocity of magneto-optical reflection response by surface plasmon excitation in the planar Au/Fe/Au/glass nano-systems with prism coupling is studied. In order to simulate diffraction response to external magnetic field theoretical matrix model based on rigorous coupled waves algorithm is applied that allows to simulate both the influence of metallic layer thicknesses and external magnetic field. The two new response factors related to response function are introduced and tested from the point of view of their applicability. Obtained theoretical results are compared with experiment realized using the measuring device Multiskop (Optrel GbR, Germany).
