单分子磁体因其磁性双稳态和慢弛豫机制而在超高密度存储材料、自旋电子器件等领域具有潜在的应用.稀土单分子磁体因为具有较大的磁矩和磁各向异性而成为近年来研究的热点话题.目前有关稀土单分子磁体的综述都主要集中在它们的合成、结构及磁性能,而在其它性质方面缺少深入而系统的研究.因此,本论文结合现有的研究成果,围绕稀土单分子磁体的高翻转能垒、复杂的多弛豫机制、可调控的磁性以及多功能材料的四个特点进行了综述,旨在更好的理解稀土单分子磁体的物理、化学本质,为稀土单分子磁体的设计与调控提供思路.
Due to their magnetic bistability and slow relaxation mechanism, monomolecular magnets have potential applications in ultra-high-density memory materials, spintronic devices, etc. Since rare earth monomolecular magnets have a large magnetic moment and magnetic anisotropy Has become a hot topic in recent years.At present, the review of rare earth single-molecule magnets are mainly focused on their synthesis, structure and magnetic properties, and lack of in-depth and systematic research on other properties.Therefore, this dissertation combines the existing research The results are summarized around the high turnover energy barrier of rare earth single-molecule magnets, the complicated multi-relaxation mechanism, the adjustable magnetic properties and the four characteristics of multi-functional materials in order to better understand the physics and chemistry of rare earth single-molecule magnets Nature, provide ideas for the design and regulation of rare earth single-molecule magnets.
