关键词: 钴–稀土单分子磁体结构磁性Co-Ln Single Molecule Magnets Structure Magnetism
摘要: 在Co(II)离子中,d轨道上总共有7个电子,其中3个为不成对电子。由于它的轨道角动量未淬灭且自旋轨道耦合相对较强,Co表现出明显的磁各向异性,使其成为磁性材料中优良且稳定的自旋载体。同时,Co容易氧化为Co,在配位环境中通常表现出抗磁性行为。这一特性在3d-4f单分子磁体(SMMs)中被用作磁稀释剂,有效抑制QTM。研究人员利用这些特性合成了许多钴–稀土(Co-Ln)SMMs。因此,本文通过对近年来典型的钴–稀土单分子磁体进行综述,以期为3d-4f单分子磁体的发展奠定一定的基础。
Abstract: In the Co (II) ion, there are a total of 7 electrons present in the d orbitals, including 3 unpaired electrons. Due to its unquenched orbital angular momentum and relatively strong spin-orbit coupling, Co exhibits significant magnetic anisotropy, making it an excellent and stable spin carrier within magnetic materials. Simultaneously, Co readily undergoes oxidation to Co, which often exhibits diamagnetic behavior in coordination environments. This property is harnessed in 3d-4f single molecule magnets (SMMs)to serve as a magnetic diluter, effectively suppressing QTM. Researchers have exploited these characteristics to synthesize numerous Co-Ln SMMs.
