Designer clusters of atoms that can mimic other elements have for the first time been devised with magnetic properties (Image: Ulises Reveles, VCU)From The New Scientist:
New "superatoms" – clusters of atoms that share electrons and can mimic the behaviour of other elements – have been devised with magnetic properties for the first time. The breakthrough provides a way to design novel nano-scale building blocks with controllable magnetic properties that could be used to make faster computer processors and denser memory storage.
Superatoms were discovered in the 1980s when Walter Knight and colleagues at the University of California, Berkeley, found that groups of sodium atoms can share electrons amongst themselves.
