摘要
简述了磁致冷的原理 ,概述了近室温磁致冷材料的研究进展 ,重点介绍了近年来近室温磁致冷材料的突破性进展及其意义 ,介绍了国内研究情况和我国研究、发展的必要性和重要意义。
The basic principle of magnetic refrigeration had been introduced. And the developments of sub room temperature magnetic refrigerants had been reviewed. Then special attention had been paid to the recent breakthrough of magnetic refrigerants with giant magnetocaloric effect such as GdSiGe alloys and perovskite type compounds. And then the research development of room temperature magnetic refrigerants in China had been introduced. Finally, the necessit and important significance of developing room temperature magnetic refrigerants in China was proposed.
