Single-Atom Magnets Store Bits Of Data

Although the team of researchers have only managed to store two bits of data in a new storage device, their developments may lead to the tiniest electronics yet.
According to a recently published study, a team of physicists and engineers have successfully stored digital data in the magnetic field of a single atom.
By encoding each bit into the magnetic field, the team has managed to develop the most compact data storage device ever.
The team used atoms of holmium deposited on a surface of magnesium oxide to store the bits.
By directing each atom’s magnetic field using a scanning tunneling microscope, the team could flip the magnetic field, and read the data by measuring the current running through the field.
