title: Tunable polar Kerr rotation spectra of glass slides by coating two-dimensional polystyrene sphere array with Au nanocaps.
abstract: For glass slides covered by two-dimensional array of polystyrene spheres with Au nanocaps on the top surface, polar Kerr rotation θ(K) peaks occur in the visible region and shift with the polystyrene sphere diameter. The θ(K) spectra arise from the spectral properties of the transmission/reflectance ratio. The observed tunable magneto-optical behavior has potential applications in magneto-optical filters.
