Bilayer composites that can show magneto-birefringence effect were fabricated based on the product effects of magnetostriction and stress-birefringence. Large magneto-optical responses were obtained under a magnetic field lower than 700 Oe at room temperature for the bilayers. The magneto-optical retardation was observed to decrease along the direction vertical to the interface, suggesting a non-uniform stress distribution along the thickness direction in the elasto-optical layer. Local action principle or Saint-Venant's principle was taken into account in analysis of the interlayer elastic coupling and the magneto-birefringence effect. The theory that was consistent with experiments was obtained.
