Growth and Characterization of Cobalt Doped Titanium Dioxide Thin Films by Pulsed Laser Deposition
Highly oriented rutile and anatase TiO(2):Co films have been grown on sapphire and SrTiO(3) substrates by pulsed laser deposition with Co concentrations of 3 % and 12 %. All films are transparent with optical gaps > 3 eV and show ferromagnetic behavior where the moment per Co ranges from 0.27 muB...

| description | Highly oriented rutile and anatase TiO(2):Co films have been grown on sapphire and SrTiO(3) substrates by pulsed laser deposition with Co concentrations of 3 % and 12 %. All films are transparent with optical gaps > 3 eV and show ferromagnetic behavior where the moment per Co ranges from 0.27 muB to 1.2 muB. The resistivity shows activated behavior where the activation energy ranges from 67 meV to 79 meV. Our results are consistent with other reports on dilute ferromagnetic TiO(2):Co films prepared under similar growth conditions. |
