The theory of vector spatial solitons in cascadable nonlinear media, bounded by magneto-optic material, is established. The main work is preceded by a discussion of the fundamental-harmonic wave phenomenon and four coupled equations for the system are established. A number of simulations are provided that illustrate both the vector nature of a quadratically nonlinear film, bounded by magneto-optic media and the crucial role of the magnetic field. It is demonstrated that the powerful polarization control exercised by the magnetic field suggests a number of interesting applications.
