Optical parametric interaction in isotropic third-order nonlinear media with magneto-optic properties is investigated. It is shown that new phase-matching conditions with a magneto-optic contribution are possible. In particular, we study four-wave mixing and electric field–induced three-wave parametric processes in the presence of a magnetic field applied along the direction of propagation of the interacting waves. Control of the new phase-matching branches can be achieved by tuning of the magnetic field.
