Abstract

By the product of magnetostriction and stress-birefringence, the laminate composites that can show Voigt effect was suggested and fabricated. Under a magnetic field no stronger than 1900 Oe, a phase difference of about 3.3π was observed for a trilayer composite Tb_1-xDy_xFe_2-y / polycarbonate / Tb_1-xDy_xFe_2-y with the polycarbonate layer in size of 5×2.75×20 mm³ at room temperature, resulting in a half-wave magnetic field of no greater than 270 Oe.
