研究领域

固态相变制冷技术包括弹热效应、磁热效应、电热效应等单场致效应，在各自的研究方向以并行方式快速发展。由于弹热效应所对应的结构相变通常伴随着磁热效应的磁相变和电热效应的电偶极子相变，弹热效应与磁场、电场等场致效应于近年来交汇融合，形成了磁场、力场、电场等多场作用下，磁熵、晶格熵和极化熵的多场转换机理和调控的新兴方向。但是，这些场致熵变的物理机制及其多场调控原理，虽已在磁力两个外场的情形得到运用，但无法解决在更复杂的力磁电多场条件下，序参量之间的转换和耦合作用对增强制冷效应和功能寿命的有效调控，严重制约了利用多场转换耦合效应大幅提升制冷性能和稳定性的发展。通过多场条件下的力电磁多场转换与调控，实现制冷效应的叠加与耦合，是固态相变制冷领域未来发展的重要方向之一。
