Superstructured Thin Film Chemistry group (M. Kawasaki's group) has succeeded in developing a transparent spintronics material based on titanium dioxide (TiO2). Co-doped TiO2 has very high Curie temperature ~600 K with a small amount of Co, and its thin film is transparent and can be grown on glass substrate. Accordingly, this compound is expected to be used for semiconductor spintronics devices operable at room temperature. This work was supported in part by New Energy and Industrial Technology Development Organization, the Industrial Technology Research Grant Program. This result appeared in such presses as Nikkei Sangyo Shimbun (Nov. 6th).
