稀土院成功研发室温磁制冷机性能综合测试系统

近日，稀土院磁制冷课题组成功研发出室温磁制冷机性能综合测试系统。经初步测试，该系统功能齐备，测试指标全面，解决了课题组多年缺乏磁制冷机检测评价手段的问题。

该测试系统具有多模态、多功能、多参数指标测试以及多运行参数连续调控等特色，不仅可以模拟测试磁制冷机在不同工况条件下的性能指标，也为磁制冷机性能提升提供基本保障，解决了多年以来无法准确测试磁制冷机制冷功率的问题。

经过多参数设定，成功使磁制冷机制冷功率突破百瓦量级，并进一步达到150瓦以上；同时，通过优化运行参数成功提升磁制冷机最大温跨突破35摄氏度以上。这些参数不仅为磁制冷机实用化提供基础数据，也将助力多项国家重点项目建设。

稀土院在磁热材料研发领域取得新突破

近日，稀土院与包头师范学院科研团队成功研发出高性能低温高熵非晶合金，在磁热材料研发领域取得了新突破。

长期以来，受限于高熵非晶合金的成分设计、非晶形成能力以及制备工艺过程中的难点，该类合金的研制与应用受到严重制约。此次研究破解了合金成分设计难题，突破传统晶态合金的磁热性能限制，首次实现自旋玻璃态与二阶磁相变的协同调控，在零下225℃到零下95℃之间的宽温区内获得优异的磁热性能，为液氢温区磁制冷提供了新的材料解决方案。
