摘要：
Single-molecule magnets: A square-pyramidal pentametallic dysprosium cluster (see picture) was synthesized and showed slow magnetic relaxation at temperatures as high as 40 K. The thermal energy barrier to relaxation of magnetization of this single-molecule magnet is 530 K and is the largest yet observed for any d- or f-block cluster compound.
