Magnetic properties of Cr-doped SnO 2 and the effects of oxygen vacancy (V O ) on the magnetic properties are examined to understand the origin of ferromagnetism in Cr-doped SnO 2 and explain the observed discrepant phenomena. Cr-doped SnO 2 shows a p-d hopping ferromagnetic interaction that decreas
## Abstract In Coβdoped SnO~2~ fivefold degenerate Coβ3d states split into five singlet states. The magnetic moment of Co is mainly contributed by the spin polarization of Coβd~__xy__~ states. The introduction of oxygen vacancies largely increases the magnetic moment of Co. The increase of Co magne
