Origin of Nonmagnetic Kramers Doublets in the Ground State of Dysprosium Triangles: Evidence for a Toroidal Magnetic Moment

Origin of Nonmagnetic Kramers Doublets in the Ground State of Dysprosium Triangles: Evidence for a Toroidal Magnetic Moment

Triangular donuts: High‐level ab initio calculations reveal a toroidal arrangement of local magnetizations at dysprosium sites in the ground state of triangular dysprosium complexes (see picture), an arrangement that explains their unusual magnetic properties.
