Optical and magneto-optical properties of Fe x Ag x superlattices with thickness ( x ) of 1, 2, and 3 atomic-layers were investigated from first-principles calculations by using full-potential linearized augmented plane wave method and Kubo formula. Based on the calculated optical conductivity tensors, the characteristic features in dielectric functions, refractive indexes, absorptions, electron loss functions, and magneto-optical constants in the Fe x Ag x superlattices were systematically elucidated. We found that the optical properties can be controlled by tuning the hybridization of d- orbitals between Fe and Ag due to changes in the thickness of superlattices.
