单分子磁体的研究进展

Progress of Research on Single Molecular Magnets

单分子磁体为纳米尺寸,磁特性源自单个分子的内部,可以独立地作为一个磁功能单元,是突破尺寸对传统磁体性能制约的一条途径。已知单分子磁体基本上是含Mn、Fe、V、Cr和一些其他金属元素的簇合物,有望用来制造分子器件、磁存储材料等。本文介绍了一些典型的单分子磁体的研究和发展趋势。

Single Molecular Magnets （SMM） could act as independent magnetically functional units since they are nano - sized compound molecules and molecular clusters. The related magnetic properties are attributed to the metallic ions interior of molecule, which indicates the dimension restrict for traditional magnets could be surmounted. SMMs representatively contain metal clusters such as Mn, Fe, V and Cr etc, and can potentially be used to produce such as molecular device and magnetic recording materials. The progress of research on SMMs are introduced this paper.
