3d过渡金属单离子磁体

Single-Ion Magnets Based on 3d Transition Metal

单分子磁体在量子计算、高密度存储材料以及分子自旋电子学等领域具有广阔的应用前景。3d过渡金属单离子磁体具有结构简单、易于研究磁构关系以及可控配体场获得高能垒等特点,因而成为近年来单分子磁体领域的研究热点。本文结合现有研究成果,从配位构型出发,旨在对近年来基于3d过渡金属离子的单离子磁体进行综述,重点阐述配体场、磁各向异性和单离子磁体性质三者之间的关系,为设计合成单分子磁体提供新的思路。

Single molecule magnets are potentially useful in quantum computing, high density data storage and molecular spintronics. 3d transition-metal-based single-ion magnets have attracted intensive interest because their structures are simple, and it is easy to explore the magneto-structural relationship, and achieve the higher barriers by tunable ligand field. Unifying the domestic and foreign research situation, the paper will show an overall perspective of the present single-ion magnets(SIMs) based on the 3d transition metal with the coordinated geometry, and highlight the relationship among the ligand field, the magnetic anisotropy and the behavior of single molecule magnet, which will provide a new route for the syntheses of single molecule magnets.
