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

Researchers have finally done it --- but just for 1.5 minutes near absolute zero

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 Zurich has taken a step toward that idea by depositing single magnetizable atoms onto a silica surface, with the atoms retaining their magnetism.

In theory, certain atoms can be magnetized in one of two possible directions: “spin up”… read more
