Abstract

A series of Co_xAg_100-x granular films was prepared by ion beam sputtering and annealed at 100 degree(s)C, 250 degree(s)C, 400 degree(s)C, 500 degree(s)C, respectively. The optical constants, the complex dielectric function and magneto-optical Kerr parameters were measured at room temperature. It was found that Kerr rotation and ellipticity with increasing of the Co content. For the samples Co₁₇Ag₈₃, the strong Kerr effect enhancement is observed around the Ag plasma edge. With the annealing temperature increasing, the enhancement peak shifted toward the low photon energy region. From the analysis of the numerical calculations, it is concluded that the magneto-optical Kerr effect enhancement is due to the presence of the steep plasma edge.
