12/03-- Shown are cobalt nanoparticles that have self-assembled into bracelet-like "nanorings." The rings' magnetic flux can be oriented in one of two directions – clockwise or counterclockwise – a characteristic that could represent binary numbers in magnetic memory devices. Because the flux direction remains even without a constant power supply, it is possible these rings could lead to so-called "non-volatile" computer memory, which would not be wiped out in the event of a system failure.
