Abstract

A magneto-optic spatial light modulator (MOSLM) driven by an electric field was fabricated, which is multiferroic device with magneto-optical garnet layer and piezoelectric PZT one. To control the direction of magnetization of the garnet layer, a stress field induced by PZT film was applied to the garnet layer. With an external magnetic field, the pixels of the MOSLM were switched. The driving current required for the magnetization switching was remarkably reduced to 500 nA, whose value was less than 1% of a driving current of the conventional current-driven MOSLM.
