An international team led by IBM has created the world’s smallest magnet, using a single atom of rare-earth element holmium, and stored one bit of data on it over several hours.
The achievement represents the ultimate limit of the classical approach to high-density magnetic storage media, according to a paper published March 8 in the journal Nature.
Currently, hard disk drives use about 100,000 atoms to store a single… read more
