An Investigation on Structure, AC Conductivity, and Dielectric Characteristics of Ni0.6Cu0.2Zn0.2Pd3xFe2-2xO4 (x ≤ 0.1) Nanospinel Ferrites

Abstract

Partially palladium (Pd) substituted Ni0.6Cu0.2Zn0.2Pd3xFe2-2xO4 (x ≤ 0.1) nano-spinel ferrites (NCZPdx (x ≤ 0.1) NSFs) have been manufactured via sol–gel combustion route. The phase of all samples has been endorsed by XRD diffraction analysis. Their crystallite size (DXRD) were estimated within 36–72 nm range. Morphology and the chemical composition have been confirmed by EDX (Energy Dispersive X-ray) and SEM-TEM (Scanning-Transmission Emission Microscopy) respectively. Complex impedance spectroscopy (CIS) was utilized to explore the dielectric characteristics within 20 to 120 ºC temperature and from 1 to 106 Hz frequency ranges.
