Abstract

Co-doped anatase TiO₂ thin films were prepared using the Co-ion-implantation method. The as-implanted film showed superparamagnetic properties due to the presence of magnetic nanoclusters, whose existence was proved by scanning transmission electron microscopy (STEM) studies. When the films were postannealed, the particle size and the blocking temperature were increased by raising the annealing temperature and/or decreasing the oxygen pressure.
