摘要: Abstract Co doped bulk SnO2 based diluted magnetic semiconductors were prepared in single-phase form up to 10% of doping. The properties studied from magnetization and electron spin resonance measurements. the 2% sample annealed under N2 gas atmosphere exhibited a saturation 0.34 μ B /Co ion it could be analysed on Brillouin function model by taking into account ferromagnetic contribution. versus field ( M – H ) curves for other samples recorded at three different temperatures analyzed bound polaron model. variation spontaneous moment with temperature doping concentration is explained detail.
