Abstract
A magneto-optical structure is provided. The magneto-optical structure includes a substrate. A waveguide layer is formed on the substrate for guiding electromagnetic radiation received by the magneto-optical structure. The waveguide layer includes magnetic oxide material that comprises ABO3 perovskite doped with transition metal ions on the B site, or transition metal ions doped SnO2, or transition metal ions doped CeO2.
