分子纳米磁体被认为是低温磁制冷的有效候选者。设计这些用于增强冷却的材料需要在分子水平上控制和优化量子特性，特别是：自旋基态、磁各向异性和存在低位激发自旋态。在这里，我们提出的理论框架，连同最近的结果，并对未来的发展前景进行了严格的审查。
Molecular nanomagnets are considered valid candidates for magnetic refrigeration at low temperatures. Designing these materials for enhanced cooling requires the control and optimization of the quantum properties at the molecular level, in particular: spin ground state, magnetic anisotropy, and presence of low-lying excited spin states. Herein, we present the theoretical framework together with a critical review of recent results, and perspectives for future developments.
