摘要
简要介绍了磁制冷的基本原理、表征及磁热效应的影响因素,综述了近期钆基无机化合物磁致冷剂的研究进展。近年来通过将碳酸根、硫酸根、磷酸根、氢氧根、卤素离子等相继引入钆基化合物,得到了一系列在超低温范围内具有高的磁熵变的钆基无机化合物,通过对这些钆基无机框架化合物的总结和讨论,探究了这类磁致冷材料的发展趋势。
This review outlines recent advances in the Gd-based inorganic refrigerants referring to the influence factor of magnetocaloric effect as well as the basic theory, characterization of magnetic refrigeration. Inorganic counterions with large charge/weight ratio, such as gallate, carbonate, sulfate, phosphates, hydroxyl and halide, have been introduced to gadolinium based（Gd-based） compounds to design dense magnetic coolants with high magnetic entropy changes on the low temperature region. This review herein explores the development trend of Gd-based inorganic magnetic refrigerants through the summary and discussion about these reported compounds.
