Abstract

The leaf-like NiFe ₂O ₄ nanostructure formed from nanoparticles has been successfully prepared on polymer assisted sol-gel method. Here ethylene glycol (EG) is used as a gelling agent as well as solvent and PVA as a capping agent. A sequence of control experiments confirms that the polymer concentration with NiFe ₂O ₄ has direct influence on the morphology of the products. Characterization of the synthesized nanoparticles and nanoleaf are carried out using powder XRD, FT-IR, TGA, HR-SEM, TEM, HR-TEM, dielectric measurements tangent, microRaman and VSM. On the basis of these experimental results, potential influence mechanisms in the growth processes are proposed.
