The First {Dy-4} Single-Molecule Magnet with a Toroidal Magnetic Moment in the Ground State
A toroidal magnetic moment in the absence of a conventional total magnetic moment was first observed in a novel tetranuclear dysprosium cluster with nonmagnetic ground state. The toroidal state is quite robust with respect to variations of the exchange parameters.
