采用单晶X射线衍射和交流磁电感受器对方形反棱镜Na[Dy(DOTA)(H2O)]中心点4H(2)O配合物进行了表征。检测到磁弛豫的两种竞争机制以及施加静磁场时弛豫时间显着增加六个数量级。
The square antiprismatic Na[Dy(DOTA)(H2O)]center dot 4H(2)O complex was characterised by single crystal X-ray diffraction and ac magnetic susceptometry. Two competing mechanisms for magnetic relaxation as well as the remarkable increase of six orders of magnitude in the relaxation time upon application of a static magnetic field were detected.
