摘要
Gd Zn稀土合金在磁场为 1 .5特斯拉 ,温度为 2 5 0~ 30 0 K范围内 ,具有较大的磁熵变 .Zn元素的加入会使合金的磁熵变温区变宽 ,且随着元素 Gd和 Zn的比例不同 ,合金的居里温度、磁熵变最大值以及温区宽度都有相应的变化 .
The alloys of GdZn with a giant magnetocaloric were measured at temperatures between 250~300 K under a magnetic field up to 1.5T . The alloys′ temperature range is lengthened with increased ratio of Zn . By adjusting the Gd:Zn ratio,the curie temperature and the magnetic entropy are changed correspondingly.
