The discovery of materials capable of storing magnetic information at the level of single molecules and even single atoms has fueled renewed interest in the slow magnetic relaxation properties of single-molecule magnets (SMMs). The lanthanide elements, especially dysprosium, continue to play a pivotal role in the development of potential nanoscale applications of SMMs, including, for example, in molecular spintronics and quantum computing. Aside from their fundamentally fascinating physics, the realization of functional materials based on SMMs requires significant scientific and technical challenges to be overcome. In particular, extremely low temperatures are needed to observe slow magnetic relaxation, and while many SMMs possess a measurable energy barrier to reversal of the magnetization (U_eff), very few such materials display the important properties of magnetic hysteresis with remanence and coercivity.

镧系单分子磁体中的环戊二烯基配体：一环可支配全部吗？

能够在单分子甚至单原子水平上存储磁信息的材料的发现激发了人们对单分子磁体（SMM）的慢磁弛豫特性的新兴趣。镧系元素，尤其是，在SMM潜在的纳米级应用开发中继续发挥关键作用，例如在分子自旋电子学和量子计算中。除了从根本上令人着迷的物理学之外，基于SMM的功能材料的实现还需要克服重大的科学和技术挑战。特别是，需要极低的温度才能观察到缓慢的磁弛豫，而许多SMM拥有可逆的磁化强度可测量的能垒（U _eff），这种材料很少能显示出具有剩磁和矫顽力的磁滞的重要性能。
