Ferroelectrics, and Some Related Applications

This is the authors' abstract. We don't add key points for this paper.

First- and second-order ferroelectric phase transitions are presented, a model of hysteresis is introduced and the electrocaloric effect is discussed, with some applications. It is suggested that high-voltage pulses may be produced by means of the electrocaloric effect, as well as an efficient cooling by means of external fields along hysteresis loops. The hysteresis heating by electrocaloric effect is discussed for comparison.
