摘要: 单分子磁体在高密度信息存储、量子计算和分子自旋电子学等方面具有潜在的应用价值。3d过渡金属单离子磁体(3d-SIMs)作为一种特殊的单分子磁体，磁构关系较为简单且易于分析，因此得到了众多研究者的关注。其中，由于钴(II)离子具有较大的磁各向异性，且为Kramers离子，所以基于钴(II)离子的单离子磁体报道居多。本文结合近年来的研究成果，对不同配位数的钴(I/II)单离子磁体的磁各向异性和慢磁弛豫行为进行了总结，分析了配位构型和配位原子等配位环境对钴(II)单离子磁体磁各向异性的影响，为单核钴离子磁体的设计与调控提供思路。
Abstract: Single-molecule magnets (SMMs) have potential applications in high-density information storage, quantum computation and molecular spintronics. As a special kind of SMMs, 3d transition-metal-based single-ion-magnets (3d-SIMs) have attracted intensive interest because of their simple structure and easily exploring the magneto-structural relationship. Among them, cobalt (II) ions are Kramer ionsand have large magnetic anisotropy, so that most reports of single ion magnets are based on cobalt (II) ions. Based on the recent research, this paper summarizes magnetic anisotropy and slow magnetic relaxation behavior of Co(I/II)-SIMs with different coordination number, and analyzes the influence of the coordination environment, including coordination geometry andcoordinated atoms, on the magnetic anisotropy of Co(I/II)-SIMs. This work will provide new routes in designing new Co(I/II)-SIMs with excellent magnetic properties.
