Abstract

This study comprehensively investigates the structural, morphological, dielectric, and conductivity properties of Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles synthesized through a hydrothermal method, focusing on their suitability for technological applications. The nanoparticles exhibited a cubic structure with an average grain size of approximately 18.89 nm. The dielectric properties were analyzed with respect to frequency and temperature, showcasing behaviors consistent with Maxwell-Wagner and Koop's theories. The dielectric plane plots, corresponding to the impedance circuit in the Smith Chart, were found to align with the Davidson-Cole relaxation model. Moreover, the conductivity properties adhered to the Jonscher Power law, resembling conductive properties akin to semiconductors in accordance with the band theory. Notably, the s parameter, indicative of the DC conduction mechanism, displayed temperature-dependent variations, suggesting compatibility with the small polar and correlated hopping barrier conduction models. The thermal activation energies of the Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles at 10 2 , 10 3 , 10 4 , 10 5 , and 10 6 rad/s frequencies have been recorded at 0.115, 0.141, 0.157, 0.133 and 0.121 eV, respectively. The experimental results strongly suggest that Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles hold promise as an inspiring material for electronic circuit applications.
