ABSTRACT
Laser ablated Cr-doped TiO2 thin films grown on LaAlO3 substrates are single phased anatase and room temperature ferromagnetic. The magnetic moment of Cr-doped TiO2 films is rather large, and it is consistent with the theoretical predictions. Magnetic force microscopy measurements certainly suggested that the strong ferromagnetism at high temperature in Cr-doped TiO2 films is intrinsic, and it must originate from the diluted magnetic matrix but not from any form of clusters.
