Ferromagnetic nanoparticles of iron and vanadium co-doped SnO2 were synthesized by a sol-gel method. Fe and V co-doped SnO2 enhanced the magnetization, which showed the maximum saturation magnetization (Ms) at 1 % of Fe and 1 % of V co-doping. With further increasing the amounts of Fe and V co-doping into SnO2 host, the Ms decreased. Chemical states of vanadium ions were deduced as V5+ states by x-ray absorption spectroscopy. Mössbauer spectrometry revealed that the intensities of sextet components are related to the Ms, which indicates that small amounts of Fe and V co-doping is effective to enhance Ms.
