中文摘要：

制约室温磁制冷技术的因素除制冷热力设计外，缺少高效率的磁致冷材料是关键。虽然目前已经发现了一系列大磁热效应材料，离实际应用还有很大距离。由于新的磁热效应主要出现在具有一级相变特点的体系中，这引起了一系列新问题，例如磁晶耦合对磁相变的影响，体系多自由度共存、相互关联以及各自由度对熵变的贡献，如何实现各类熵变的共振增强以获得最大的磁热效应等，所有这些为新物理现象的发现提供了机会，也对传统的磁热效应理论提出了巨大的挑战。通过本项目的研究，目的是（1）丰富和发展磁热效应的理论和方法；（2）找到影响磁热效应的主要因素以及控制磁热效应的最佳途径；（3）揭示大磁热效应的物理机理；（4）合成具有低场大磁熵变、高响应、磁相变温度连续可调的新型磁熵变材料；（5）解决磁制冷工质的加工工艺及其稳定性和耐腐蚀性等与材料使用密切相关的问题。

中文主题词： 室温磁致冷材料；相变；磁熵变与磁热效应
