摘要
本文综述了反钙钛矿结构负热膨胀材料,阐述了磁相变与材料负热膨胀性能之间的联系,对不同体系Mn3XN材料的负热膨胀特性进行了对比,分析了相互之间的膨胀系数及其负热膨胀的响应区间,并对该材料的应用前景和今后的研究方向进行了展望。
A large magnetostriction in an antiperoviskite system, Mn3XN, is well-known for their large magnetovolume effect. The relation of magnetic transformation and negative thermal expansion was discussed. The contrastive difference of several Mn3 XN system was summarized, and the diversification of the linear thermal expansion with different element replacement was analyzed. It is proposed with a view to practical applications and further experiment.
