Abstract

This study investigates the electrical transport features of V₂O₅ added Li-Zn ferrites. The ferrites have the compositions Li₀.25Zn_0.50Fe_2.25O₄ + xV₂O₅ (where x = 0.4, 0.8 and 1.2 wt %) and are prepared by the solid-state reaction technique. Frequency-dependent dielectric constant and ac conductivity of the samples have been investigated at room temperature. An enhancement of dielectric constant and ac conductivity is observed with V₂O₅ addition and displayed a decreasing trend for higher V₂O₅ addition. The Nyquist impedance plots of the samples display a single semicircular arc, indicating that the conduction mechanism of Li-Zn ferrites occurs through the grain property.
