Anomalies of dielectric properties in a lithium-titanium ferrite ceramic

Abstract

For the first time a dielectric hysteresis is observed in a polycrystalline lithium-titanium ferrite in the temperature range 475-575 K. A thermal Barkhausen effect is detected during heating and cooling of ferrite specimens prepolarized in an electric field. The results provide evidence on the formation of properties similar to ferroelectricones in lithium-titanium ferrites under certain conditions.
