Abstract :

Dielectric phenomenon have been investigated by synthesizing nano-particles of Ni CuxZn Fe O ferrites wherein (0.8-x)Ni2+ ions have been replaced by xCu2+ ions 0.8-x 0.2 2 4 (x = 0.0 0.6 with steps of 0.2) by sol-gel auto-combustion technique. The crystal phase of samples was confirmed by employing powder X-ray diffraction technique. The variation of dielectric parameters such as dielectric constant (E’), dielectric loss (E”) and dielectric loss tangent (tan) as a function of frequency and composition have been investigated. The dielectric behavior showed a typical ferrite nature for all compositions. The loss tangent (tan ) measurements conclude that the conduction mechanism in these samples is due to polaron hopping.
