TiO2 doped with Cr has been investigated using density functional theory with the Hubbard term (DFT+U), In addition to electronic properties, we have also investigated the magnetic properties Cr-doped TiO2. Among the crystal structure investigated includes rutile, anatase and brookite TiO2. From the study we observed that, between 0-5% Cr doping, the systems displayed a paramagnetic behavior while between 6-8% the systems exhibit ferromagnetic characteristics. The magnetic moment was found to increase with the increase in doping percentage upto 6%, above 6% the magnetic moment remained constant (~2µB) indicating magnetic saturation. The anatase structures highly favors Cr doping than rutile and brookite.
