TiO2 thin films doped or mixed with cobalt oxide were grown by atomic layer deposition using titanium tetramethoxide and cobalt(III)acetylacetonate as metal precursors. The films could be deposited using both 03 and H2O as oxygen precursors. The films grown using water exhibited considerably smoother surface than those grown with ozone. The TiO2:Co films with Co/(Co + Ti) cation ratio ranging from 0.01 to 0.30 were crystallized by annealing at 650 C, possessing mixed phase composition comprising rutile and anatase and, additionally, CoTiO3 or CoTi2O5. The annealed films demonstrated magnetic response expressed by magnetization curves with certain hysteresis and coercive fields.
