Description

We have studied the magneto-optical Kerr effect and optical reflectance of perpendicular magnetized Co/Pt films on self-assembly two-dimensional polystyrene spheres. It is shown that the magneto-optical and the reflectance spectra are correlated to each other. Calculations have shown that the magneto-optical Kerr rotation and the Kerr ellipticity spectra are governed by the resonant coupling of light to the excitations of surface plasmon polaritons and modified by the sphere diameters. These effects lead to the possibility of developing new magnetoplasmonic nanosensors.
