Sažetak

In this work, we report the room temperature
ferromagnetism in Sn1‐xFexO2 and Sn1‐xNixO2 (x = 0.00, 0.03
and 0.05) nano‐crystalline powders. All the samples were
prepared using co‐precipitation method. X‐Ray
Diffraction (XRD), transmission electron microscopy
(TEM), energy dispersive x‐ray analysis (EDAX), UV‐
visible absorption spectroscopy and room temperature
magnetization measurements were performed to study
the crystal structure, morphology, elemental analysis,
optical band gap and magnetic properties of Fe and Ni
doped SnO2. TEM results depict the formation of
spherically shaped and small sized nanoparticles of the
diameter of ~ 3 nm.  The band gap energy of the Fe and
Ni doped samples found to decrease with increasing their
concentrations. The higher saturation magnetization was
observed in low concentration Fe and Ni doped tin oxide.
