Abstract
The SrTiO 3/TiN bilayers were used as a buffer for the epitaxial growth of Co-doped anatase TiO 2 thin films on silicon. The layers were sequentially formed by pulsed laser deposition and ferromagnetism was observed at room temperature with a coercivity of 607 Oe. High-quality epitaxy of films on the silicon was demonstrated by x-ray diffraction and transmission electron microscopy. The results show that the ferromagnetism is due to the highly cobalt enriched TiO 2 clusters which nucleate after a certain growth of film.
