我们给出了一个镝三角形分子磁体的零场Muon自旋晶格驰豫测量结果。注入的µ子探测到的局域磁场表明，在T*以下有静态和动态的内部磁场共存，类似于35K，磁化强度和热容测量表明，在这一温度以下没有磁有序的迹象。我们将静电场归因于Dy-3基态磁化强度的缓慢弛豫。在低温下，田间动态部分的波动时间估计与0.55亩S相似。
We present zero field muon spin lattice relaxation measurements of a Dysprosium triangle molecular magnet. The local magnetic fields sensed by the implanted muons indicate the coexistence of static and dynamic internal magnetic fields below T* similar to 35 K. Bulk magnetization and heat capacity measurements show no indication of magnetic ordering below this temperature. We attribute the static fields to the slow relaxation of the magnetization in the ground state of Dy-3. The fluctuation time of the dynamic part of the field is estimated to be similar to 0.55 mu s at low temperatures.
