“…The dielectric properties of Ni-Zn ferrites in the frequency range 10' to lo5 Hz have been investigated by Murthy and Sobhanadri [3]. The dependence of dielectric properties of mixed Li-Zn ferrites on the composition and frequency has been studied by Ravinder and Seshagiri Rao [4].…”

The dielectric constant (\documentclass{article}\pagestyle{empty}\begin{document}$ \varepsilon ' $\end{document}) and dielectric loss tangent (tan δ) of mixed Li‐Cd ferrites of various compositions are measured at room temperature in the frequency range 1 to 100 kHz using a capacitance bridge. Plots of dielectric constant (\documentclass{article}\pagestyle{empty}\begin{document}$ \varepsilon ' $\end{document}) versus frequency show a normal dielectric behaviour of spinel ferrites. The frequency dependence of dielectric loss tangent (tan δ) is found to be abnormal, giving a peak at a certain frequency for all the samples of Li‐Cd ferrites. However, Li0.3Cd0.4Fe2.3O4 does not show a peak in the frequency range 1 to 100 kHz. A qualitative explanation is given for the composition and frequency dependence of the dielectric constant and dielectric loss tangent. The dielectric constant for these mixed ferrites is approximately inversely proportional to the square root of the resistivity.
