Dielectric properties of the lithium-titanium ferrite ceramics in a wide frequency range

Electrophysical properties of the Li-Ti ferrite ceramics with the spinel structure (Li$_{0.649}$Fe$_{1.598}$Ti$_{0.5}$Zn$_{0.2}$Mn$_{0.051}$O$_4$) are studied in the frequency interval 0.5–2.5 GHz at temperatures ranging from room temperature to 530 K. The thermal emf of the ferrite ceramic samples is studied. It is demonstrated that the sample under study exhibits electron conduction. The calculated results are used to interpret the conduction mechanism using the hopping model.
