摘要
由于单分子磁体在纳米级的信息存贮和量子计算机制造等方面具有潜在的重要应用,该领域已成为化学和材料科学中最为活跃的研究领域之一.稀土Dy3+离子具有很大的内在磁各向异性,且基态能级与第一激发态能级间的能隙和磁量子数(mJ)值很大,所以稀土Dy单分子磁体具有高能垒(Ueff)值,是构筑单分子磁体的理想4f过渡金属离子.文章综述了稀土Dy单分子磁体的合成,结构和磁性的研究进展.
The potential application importance in the technology of nano-scale information storage and quan- tum computer manufacturing leads its research to be one of the most active research fields in chemistry and ma- terials science. The Dy-SMMs have high energy barrier values （Ueff）, which are the ideal 4f transition metal ions to construct single-molecule magnets because rare earth Dy3＋ ion boasts not only high magnetic anisotropy, but also high energy gap and magnitude quantum number （mj） between ground and first-excited state. The research progress on syntheses, structures and magnetic properties of Dy-SMMs is reviewed in this paper.
