Molecular Design for Cryogenic Magnetic Coolants

摘要: The area of molecular magnetic coolants has developed rapidly in recent years. A large number competitive candidates have been reported, with the cooling performances chasing each other. In this account, four explicit strategies, namely, increasing ground-state spin, reducing anisotropy, weakening interactions, and lowering weight, are proposed from theoretical viewpoint towards improving magnetocaloric effect (MCE). According to guidance, these successful strategies discussed pursue excellent coolants. This is accompanied by a discussion representative examples reported our group. entropy change increases one compound another, which most pronounced cases suggestive being largest MCE
