Magneto-optical Faraday effect has been investigated for 3d-transition-metal-substituted titania nanosheets Ti1−xMxO2 (M=Fe,Co). In Ti0.8Co0.2O2 and Ti0.6Fe0.4O2 nanosheets, a strong magneto-optical response (∼104deg∕cm) appeared near the absorption edge at 260nm. We find that tailoring magneto-optical properties could be achieved by (Fe∕Co) cosubstitution and an optimally doped Ti0.75Fe0.1Co0.15O2 nanosheet exhibits a gigantic magneto-optical response (∼105deg∕cm) over the wide wavelength region (400–750nm). By analyzing electronic structures from first-principle calculations, we have clarified that the d-d transitions are responsible for the gigantic signal in (Fe∕Co)-cosubstituted nanosheets.
