Abstract :
The Kerr rotation for light reflection from a bilayered structure composed of an electro-optic semiconductor film and a slab with high values of magneto-optic and magneto-electric interactions is theoretically investigated. The influence of a dc external electric field on the optical plane rotation angles is analyzed. The influence of frequency dispersion of the system permittivities on the Kerr rotation is studied.
