摘要
简要叙述了磁制冷的基本原理和历史发展。着重阐述了稀土—过渡族金属间化合物 Gd—si—Ge系合金及钙钛矿型锰氧化物的磁热效应及其巨磁热效应机理,对高温磁制冷工质材料的研 究现状及磁制冷技术的发展前景进行了分析。
The basic principle and the developing process of magnetic refrigeration are briefly described . The mechanism of magnetothermal effect and gigantic magnetothermal effect of, RE - TM compound, Gd - Si - Ge series alloy, and perovskite - type manganese oxides are stated emphatically. The present research of magnetic refrigeration working material at high temperature and the development prospect of magnetic refrigeratory technology are analyzed.
