摘要
The non-reciprocity of magneto-optical reflection response by surface plasmon excitation in a planar glass/Fe/Au/air system with prism coupling is studied. We aim to find the optimal thicknesses of metallic layers with regard to the reflectance sensitivity to an external magnetic field. For this purpose, a corresponding response factor is introduced and applied. The numerically modeled prediction of sensitivity is verified by experimental measurements. (C) 2012 Elsevier B.V.
