中文摘要：

分子基低温磁制冷材料因其可能替代稀缺昂贵的3He实现低温制冷而备受关注。由于GdIII具有较大的自旋基态、低自旋激发态和单离子各向同性,Gd基分子基低温磁制冷材料近年来发展迅速。结合本课题组近年来的工作及国内外相关的研究报道,介绍四类Gd基低温磁制冷材料的构筑策略：Gd簇分子基磁制冷材料、Gd基配位聚合物分子基磁制冷材料、Gd-过渡金属簇合物磁制冷材料、Gd-异金属聚合物分子基磁制冷材料;同时也对Gd基低温磁制冷材料的发展趋势予以展望。

英文摘要：

Molecular magnetic refrigeration has received much interest due to the possibility of substituting the expensive and increasingly rare He-3 in ultralow-temperature refrigeration. Because of large spin ground state,low-lying excited spin states,and singe ion isotropy for GdIIIion,Gd-based magnetic refrigerants have reached great development. In this review,the basic introduction to magnetic refrigerants was given in the first section. In the following section,the construction strategy towards four kinds of Gd-based molecular cryogenic magnetic coolers（molecular cryogenic magnetic coolers based on Gd-clusters,Gd-coordination polymers,Gd-transition metal cluster,Gd-heterometallic coordination polymers） was presented based on the works of our group and other groups. Finally,the development trends of this area were evaluated.
