A magneto-optical tunable device based on a one-dimensional magnetophotonic crystal infiltrated with a nematic liquid crystal has been proposed. By applying a tunable electric field the voltage-induced reorientation of the director results in an alternating magneto-optical effect. The transfer matrix method was performed to verify the controllable magneto-optical properties. The present results may be useful for future application of liquid crystal-based tunable magneto-optical devices.
