磁热材料:寻找新系统

Magnetocaloric materials: the search for new systems

Karl G. Sandeman

摘要:

室温下高效固态制冷的前景推动了对磁冷却发动机设计和基于磁性相变的制冷剂的研究。在这个观点阿什比风格的地图磁制冷剂的性能构建,比较流行的材料与来自理想化的一阶过渡模型的限制。这种比较表明了通过在原子、纳米和微米尺度上的结构控制和优化建立新的磁热材料系统的潜力。

英文摘要:

The prospect of efficient solid state refrigeration at room temperature is driving research into magnetic cooling engine design and magnetic phase transition-based refrigerants. In this Viewpoint an Ashby-style map of magnetic refrigerant properties is constructed, comparing popular materials with limits derived from an idealised first order transition model. This comparison demonstrates the potential for new magnetocaloric material systems to be established through structural control and optimisation at the atomic-, nano- and micro-scale.
