The effects of Fe-doping and Fe–N-codoping on the magnetic properties of SnO 2 , prepared by chemical co-precipitation technique, are investigated in details. We found that the paramagnetism is the dominant magnetic interaction in Fe doped SnO 2 . A weak antiferromagnetic coupling between Fe 2+ ions is also confirmed through Zero field-cooled (ZFC) and field-cooled (FC) magnetization studies. On the other hand, hystersis behavior is observed for Fe–N-codoped SnO 2 samples with coercivity H c ∼420 and 352Oe for x=0.05 and 0.10, respectively. As no other secondary or impurity phase is detected by XRD study and the presence of N is confirmed by EDX analysis, this observed ferromagnetism is originated due to the substitution of N in Sn 1−x Fe x O 2 . N doping at the oxygen site can be regarded as defect and introduces a hole in this system. As a result, a hole-induced ferromagnetism might be the origin of the observed ferromagnetism in Fe–N-codoped SnO 2 samples.
