Abstract

A series of [formula omitted] granular films was prepared by ion sputtering, and some of them were annealed. Both the complex dielectric function and magneto-optical polar Kerr spectra of the samples were measured in the 1.5–4.5 eV photon energy range at room temperature. There are broad peaks in the 2.5–3.5 and 3.2–4.5 eV range in the Kerr rotation and ellipticity spectra, respectively. The Kerr intensities increase with increasing Ni composition. For sample [formula omitted] the Kerr peaks are redshifted, with reduced intensities after annealing. Both the off-diagonal terms of the dielectric tensor and the optical constants are attributed to enhancement of the Kerr effect in a particular spectral range for the metal–insulator granular films.
