镧系离子由于具有大的磁动量和各向异性，被认为是单分子磁体的理想候选元素。我们已经建立了[Dy_2Cu]配合物作为一个新的SMM。在4f-3d异质金属SMM中首次提出了一种合理的磁化量子隧穿机制。Dy和Cu离子间的磁耦合参数为-0.155K。
Lanthanide ions are supposed to be promising candidates for the elements of single-molecule magnets (SMMs) because of the large magnetic momentum and anisotropy. We have established the [Dy2Cu] complex as a new SMM. A plausible mechanism for quantum tunneling of magnetization is proposed for the first time among the 4f-3d heterometallic SMMs. The magnetic coupling parameter between Dy and Cu ions was well-defined as -0.155 K.
