'Odds are good for bucky magnets'
(Article Precis, 26/Sep/1998, Issue 2153, p17)
Lila Guterman reports on the successful creation by Israeli
chemists of extremely small magnets that have similar structures to
buckyballs and nanotubes.
Less than 50 nanometres across, the devices are made from nickel
chloride, a substance which is not normally magnetic. However, the
researchers have shown that an extremely thin layer of nickel
chloride with an odd number of layers does exhibit magnetic
Since the magnetic zones in modern hard disks are much larger than 50
nanometres, this new work could offer a two-order-of-magnitude
increase in data density.
