摘要：
Performing state of the art ab initio studies, we predict that new 3d magnetic nanostructures and superlattices on Cu(111) can be stabilized by surface-state electrons. We reveal that magnetic states in these systems are determined by long-range exchange interaction between adatoms. Atomic scale simulations indicate that 3d superlattices on Cu(111) can be stable up to 25-30 K.
