摘要

在475 ~ 575 K温度范围内，首次观察到锂钛铁氧体的介电迟滞现象。在电场预极化铁氧体试样的加热和冷却过程中，检测到热巴克豪森效应。研究结果为锂钛铁氧体在一定条件下形成类似铁电子体的性质提供了证据。

Anomalies of dielectric properties in a lithium-titanium ferrite ceramic

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.
