Holmium Element Is The Key To Single-Atom Storage

Individual holmium atoms adsorbed on magnesium oxide films can form highly stable magnets, according to a study done by Fabian Natterer at Switzerland’s Federal Institute of Technology in Lausanne (EPFL) and colleagues. The team showed that the single-atom magnets can endure relatively high temperatures and strong external magnetic fields. The work could lead to the development of extremely high-density data storage devices.
