Nickel 'nanodots' could mean tiny hard drives
Nanoscopic dots of nickel that could be used to store terabytes of data in a
computer chip just a few centimetres wide have been created by US researchers.
Each "nanodot" consists of a discrete ball of several hundred nickel atoms and
can have one of two magnetic states. This allows them hold a single bit of
information, as a "1" or a "0".
In a conventional computer hard drive, information is stored on a disk coated
with a magnetic material, and bits must be far enough apart not to interfere
with each other. Nanodots should allow bits to be packed closer together as the
dots are discrete units that are not structurally linked.
Ashutosh Tiwari and Jagdish Narayan at North Carolina State University have
created nickel nanodots measuring about 5 nanometres in diameter - about 10
times smaller than those previously produced.
