Designer magnetic superatoms

摘要: The quantum states in metal clusters are grouped into bunches of close-lying eigenvalues, termed electronic shells, similar to those atoms. Filling the shells with paired electrons results local minima energy give stable species called magic clusters. This led realization that selected mimic chemical properties elemental atoms on periodic table and can be classified as superatoms. So far work superatoms has focused non-magnetic species. Here we propose a framework for magnetic by invoking systems have both localized delocalized states, which stabilize moments filled nearly-free electron lead An isolated VCs(8) ligated MnAu(24)(SH)(18) shown such superatoms' assemblies could ideal molecular devices, coupling altered charging or weak fields.
