| This image depicts the molecular magnet called chromium-8 (Cr8). The structure contains eight electrically charged chromium atoms linked in a ring that measures less than one nanometer, or billionth of a meter, across. Using this very small magnet, an Ohio State University physicist and his colleagues have demonstrated for the first time a type of magnetic behavior that was predicted to exist more than 50 years ago. The finding could help bridge the gap between quantum and classical approaches for understanding these tiny structures, and aid the future development of useful devices based on nanotechnology, such as very powerful, very small computers.
