Magnetically storing a bit on a single atom — the ultimate future data storage

Magnetically storing a bit on a single atom — the ultimate future data storage

“Dysprosium atoms (green) on the surface of nanoparticles can be magnetized in one of two possible directions: “spin up” or “spin down.” (credit: ETH Zurich / Université de Rennes)

Imagine you could store a bit on a single atom or small molecule — the ultimate magnetic data-storage system. An international team of researchers led by chemists from ETH Zurichhas taken a step toward that idea by depositing single magnetizable atoms onto a silica surface, with the atoms retaining their magnetism…”
