Optical and magneto-optical properties of copper-nickel compound metal island films.
The optical properties of copper Cu-Ni compound metal island (CMI) films composed of nanoclusters of an alloy of Cu and Ni have been experimentally investigated. The spectral characteristics of the Cu-Ni CMI films are intermediate between those of conventional Cu and Ni island films in visible and near-IR regions. In addition, the magneto-optic effect has been observed in the Cu-Ni CMI films. It is also shown that the Faraday rotation in the Cu-Ni CMI films can easily be controlled by selection of the mixture ratio of Cu and Ni.
