Separation of two factors influencing the Faraday effect in the thin film structure \(Tb_2O_3\)/Fe, namely, interference and f–d interaction of the Tb2O3 and Fe layers, is performed. As shown, the interaction of the layers enhances the Faraday effect with a maximum at a Tb2O3 layer thickness of 40 nm. The highest enhancement is by two times, and the largest specific Faraday angle is 1.8?106 deg/ñm. The enhancement increases with thickening of Fe film from 40 nm to 120 nm and disappears at a thickness of 30 nm and below. It is provided with the action of both single spontaneous and combined spontaneous and induced magnetizations of Fe film.
Keywords: Faraday effect, f–d interaction, thin film, terbium oxide, magnetization
