Electrical and magnetic properties of ZrO2-doped lithium-titanium-zinc ferrite ceramics

Research output: Contribution to journalArticle

Abstract

This report documents the effect of 0–3 wt% ZrO2 additive on the electrical and magnetic properties of LiTiZn ferrite. Ferrite powder of Li0.65Fe1.6Ti0.5Zn0.2Mn0.05O4 composition was synthesised at 900 °C for 4 h in air. Ferrite ceramics doped with ZrO2 were sintered at 1010 °C for 2 h in air. A spreading resistance analysis showed that LiTiZn ferrites exhibited nonuniform distribution of depth DC resistivity, which varied in the range of (0.25–2.3) × 109 Ω⋅cm depending on the amount of additive. Zirconia also affected the magnetic properties of ferrite so that the magnetisation increased and the initial permeability decreased as the ZrO2 content increased. In addition, the Curie temperature varied. The permeability spectra measured in the frequency range from 10 MHz to 18 GHz changed depending on the zirconia content.
