A dysprosium based single-ion magnet is synthesized and characterized by the angular dependence of the single-crystal magnetic susceptibility. and effective electrostatic analyses are performed using the molecular structures determined from single crystal X-ray diffraction at 20 K, 100 K and 300 K. Contrary to the common assumption, the results reveal that the structural thermal effects that may affect the energy level scheme and magnetic anisotropy below 100 K are negligible.
合成了一种基于镝的单离子磁体，并通过单晶磁化率的角度依赖性对其进行了表征。利用在20K、100K和300K下通过单晶X射线衍射确定的分子结构进行了有效的静电分析。与通常的假设相反，结果表明，在100K以下可能影响能级图和磁各向异性的结构热效应可以忽略不计。
