Single-molecule magnets (SMMs) have attracted much attention due to their potential applications in molecular spintronic devices. Rare earth SMMs are considered to be the most promising for application owing to their large magnetic moment and strong magnetic anisotropy. In this review, the recent progress in rare earth SMMs represented by mononuclear and dinuclear complexes is highlighted, especially for the modulation of magnetic anisotropy, effective energy barrier (U) and blocking temperature (T). The terbium- and dysprosium-based SMMs have a U of 1541 cm and an increased T of 80 K. They break the boiling point temperature of liquid nitrogen. The development of the preparation technology of rare earth element SMMs is also summarized in an overview. This review has important implications and insights for the design and research of Ln-SMMs.
单分子磁体（SMMs）因其在分子自旋电子器件中的潜在应用而备受关注。稀土单分子磁体因其大磁矩和强磁各向异性而被认为是最具应用前景的。在本综述中，重点介绍了以单核和双核配合物为代表的稀土单分子磁体的最新进展，特别是对磁各向异性、有效能垒（U）和阻塞温度（T）的调控。基于铽和镝的单分子磁体具有1541 cm的U和80 K的升高的T。它们突破了液氮的沸点温度。还概述了稀土元素单分子磁体制备技术的发展。本综述对镧系单分子磁体的设计和研究具有重要意义和启示。
