The transition metal ions doped with TiO2 films are of magnetic properties at room temperatures and have stimulated many scientists to study other properties. The Co-TiO2 sandwich composite films have been recently grown on glass and silicon substrates by using alternately radio frequency reactive and direct current magnetron sputtering. The microstructural properties of these films were characterized with Raman spectra and X-ray photoemission spectra (XPS). It shows an anatase TiO2 containing Co nano-layer. Optical absorption spectra have red shift with Co nano-layer increasing, which originated from the quantum confinement and tunnel effects. Magnetic properties show that the saturation magnetization, remanent magnetic induction and coercivity are about 4.35 emu /g, 1.02 emu/g and 569.6 Oe respectively for 12 nm Co layer between the two TiO2 layers.
