Magnetodielectric Effect in a Triangular Dysprosium Single‐Molecule Toroics

Wang, Yu‐Xia / Zhou, Yicheng / Ma, Yinina / Lu, Peipei / Zhang, Yi‐Quan / Sun, Young / Cheng, Peng

Single‐molecule toroics are molecular magnets with vortex distribution of magnetic moments. The coupling between magnetic and electric properties such as the magnetodielectric effect will provide potential applications for them. Herein, the observation of significant magnetodielectric effect in a triangular Dy3 crystal with toroidal magnetic moment and multiple magnetic relaxations is reported. The analysis of magnetic and electric properties implies that the magnetodielectric effect is closely related to the strong spin‐lattice coupling, magnetic interactions of Dy³⁺ ions, as well as molecular packing models.
