Özet

We reported on the synthesis and analysis of the composition, micro-structure, ac-dc conductivity performance and dielectric permittivity of triethylene glycol (TEG) stabilized MnxCo1-xFe2O4 nanoparticles obtained by polyol method. Crystallite size from XRD and particle size from TEM micrographs are consistent with each other. Conductivity measurements were performed to investigate the influence of the coating with TEG on the conduction characteristics of MnxCo1-xFe2O4 NP's. The frequency-dependency of the ac conductivity shows electrode polarization effect. The dc conductivity is strongly temperature dependent and shows maximum conductivity of about 5 x 10(-5) S cm(-1) for x = 1.0 at 120 A degrees C. Analysis of dielectric permittivity functions suggests that ionic and polymer segmental motions are strongly coupled.
