Abstract :

The nanoparticles of Ni1-XZnXFe2O4 (NZF) with stoichimetric proportion ‘x’ varying for 0, 0.5,1. were synthesized by sol-gel auto combustion method; the x-ray diffraction analysis confirms that the system exhibits polycrystalline single phase cubic spinel structure. The particle size estimated using scherrer formula and is confirmed by scaning electron microscope (SEM) and transmission electron microscope (TEM). This revels the formation of nanocrystalline ferrites. The dielectric constant of NZF is found to be less as compare to bulk sample, the migration of Fe3+ ion from octahedral site to tetrahedral site decreases the dielectric constant with increases zinc concentration. Conduction occurs due to charge libration and electron hopping this type of mechanism present in this compound
