Abstract: The structural and magnetic properties of the NiFe2O 4-SnO2 composite, obtained by ball-milling during different times, were investigated by X-ray diffraction, small-angle X-ray scattering, Mössbauer spectroscopy and vibrating sample magnetometry. The results showed the reduction of the crystalline particle size and modification in the nature of the system interfaces as a consequence of the mechanical treatment. Specimens with smaller particles displayed strong superparamagnetism. Large variation of the hysteresis loops for the different milling times was observed. © 2003 Elsevier B.V. All rights reserved.
