Abstract
We report recent experimental results on the mag- netic, magnetotransport, and magneto-optical properties of Co- and V-doped TiO2−δ magnetic oxides at the doping level around 1 at. %. The samples were prepared using rf magnetron sputtering in identical conditions that allows to compare the mechanisms of above-room-temperature ferro- magnetism observed in both cases of doping. In spite of the comparable values of magnetic moment around 1 ÷ 2.5 µB per 3d impurity derived from macroscopic magnetic mea- surements for both systems, the magneto-optical response
