摘要：

1-5% Fe and 1% Co co-doped SnO2 samples were synthesized by sol-gel method. Their magnetization increased with increasing crystal size of rutile SnO2. Their Mossbauer spectra contain a broad sextet, magnetic relaxation components, and paramagnetic doublet peaks for less than 3% Fe doping. The sextet of alpha-Fe2O3 was observed instead of magnetic relaxation peaks for Fe doping of above 4%. The broad sextet and relaxation components may be related to the magnetic properties of Fe and Co co-doped SnO2.
