Abstract :

ZnFe₂O₄ nanoferrites were synthesized using sol–gel technique. As–prepared and the annealed samples were examined for their structural and magnetic properties using X–ray diffraction, IR spectroscopy, scanning electron microscopy and viating sample magnetometer. The XRD analysis showed that the as–prepared sample was non–homogenous were as the annealed sample showed single phase and ferrite phase. The grain size in both the samples was observed to be 15 nm and 30 nm. The nanosize natures in the prepared samples were identified using SEM analysis. IR analysis was used to identify the ferrite phase and associated chemicals during the synthesis. Magnetization measurements revealed that pure sample showed paramagnetic behavior and impure sample showed ferromagnetic behavior.
