摘要

对含四面体和八面体离子基的铁电体和铁弹性材料进行了气压热效应和压电热效应分析。讨论了结构紊乱程度在这两种效应形成中的作用。揭示了三临界点附近不同距离相变时的热响应特征。研究材料的强压电各向异性为延长冷却循环的工作温度范围提供了方便的工具。铁弹性材料和铁电材料进行一阶转换的一个重要优点是在一种材料中结合了低热滞后和对静水和/或单轴压力的高灵敏度。

Features of the formation of baro- and piezocaloric effects in ferroelastics and ferroelectrics

The analysis of baro- and piezo-caloric effects in ferroelectrics and ferroelastics containing tetrahedral and octahedral ion groups in the structure is carried out. The role of the degree of structural disorder in the formation of both effects is discussed. The features of the caloric response at phase transitions of different proximity to the tricritical point are revealed. The strong piezocaloric anisotropy of the studied materials is a convenient tool for extending the operating temperature range of the cooling cycle. An important advantage of ferroelastics and ferroelectrics undergoing transformations of the first order is the combination in one material of low thermal hysteresis and high sensitivity to hydrostatic and/or uniaxial pressure.
