Ferromagnetism at room temperature with a large magnetic moment in anatase V-doped TiO_2 thin films

V-doped TiO_2 thin films were grown by laser ablation on LaAlO_3 substrates. In the chosen range of the growth conditions, all V:TiO_2 films have an anatase structure and exhibit semiconducting and ferromagnetic behaviors at room temperature. V:TiO_2 films have a giant magnetic moment and they seem to be far better ferromagnetic than Co/Fe/Ni-doped TiO_2 films. This study has proved that a few percent of V substituting for Ti in TiO_2 can result in a potential diluted magnetic semiconductor
