Time-domain synchrotron Mössbauer spectroscopy (SMS) based on the Mössbauer effect of Dy has been used to investigate the magnetic properties of a Dy -based single-molecule magnet (SMM). The magnetic hyperfine field of [Dy(Cy PO) (H O) ]Br ⋅2 (Cy PO)⋅2 H O⋅2 EtOH is with B =582.3(5) T significantly larger than that of the free-ion Dy with a H ground state. This difference is attributed to the influence of the coordinating ligands on the Fermi contact interaction between the s and 4f electrons of the Dy ion. This study demonstrates that Dy SMS is an effective local probe of the influence of the coordinating ligands on the magnetic structure of Dy-containing compounds.
基于Dy的穆斯堡尔效应的时域同步辐射穆斯堡尔谱（SMS）已被用于研究基于Dy的单分子磁体（SMM）的磁性。[Dy(CyPO) (H₂O) ]Br ⋅2 (CyPO)⋅2 H₂O⋅2 EtOH的磁超精细场为B =582.3(5) T，明显大于具有H基态的自由离子Dy的磁超精细场。这种差异归因于配位配体对Dy离子的s电子和4f电子之间费米接触相互作用的影响。这项研究表明，Dy SMS是一种有效的局部探针，可用于研究配位配体对含Dy化合物磁性结构的影响。
