We have been developing a magneto-optical light modulator driven by current-induced domain wall motion for a holographic display application. The device consists of a magnetic nanowire for light modulation and two tiny hard magnets to control the switching property of the nanowire. In this paper, we report on the fabrication of a light modulator with dimensions of 0.5$times$2 $mu$m2 and the successful magnetization reversal by current injection. Furthermore, we fabricated a high-density light modulator array and formed a diffraction grating consisting of different magnetization directions by applying an external magnetic field. We report the results of light diffraction measurements using the arrays. |
