摘要：
In this study a series of spinel ferrites having formula Ni(1-X)ZnXFe2O4 and substituted with Zn (where X = 0-1, Delta X = 0.2) were prepared by sol gel auto-combustion route using microwave. The crystallite size and its morphology have been analysed by TEM. The average particle size obtained from TEM is about 24-26 nm. EDX study is applied to confirm the elemental compositional proportion of prepared ferrite powder. FTIR analysis revealed the presence of characteristic absorption bands corresponding tetrahedral and octahedral sites confirmed the ferrite samples are formed. The temperature and frequency dependent dielectric properties were studied with impedance analyser. The Maxwell Wagner grain and grain boundary layer model of poly-crystalline ferrite can explain the enhancement of AC conductivity with frequency. (C) 2020 Elsevier Ltd. All rights reserved.
