Abstract

The nature of observed ferromagnetism and spin polarization in Co-doped anatase TiO₂ thin films was investigated. The Current-voltage characteristic of heterojunction did not show any dependence on magnetic field. It was found that the changes in the magnetic properties were closely related with the microstructural changes which were due to the formation of cobalt nanoclusters.
