Scientists from the University of Radbud found a new mechanism for magnetic storage of information in one atom at room temperature based on the change in the energy levels of cobalt electrons.
The former changes in the state of individual elementary particles were carried out under conditions of extremely low temperatures, which prevented their use in a commercial scale. This is due to the instability of atoms and their susceptibility to environmental changes. Radbud University researchers found a stabilization method in room temperature.
As a basis, they took the electromagnetic properties of an atom, which, like the Earth, has various poles. However, in contrast to the planetary, under normal conditions, they are constantly moving. Physics found that the placement of individual cobalt atoms in a special substrate, semiconductor black phosphorus, solves this problem without the need for cooling. After achieving stability, they were able to manipulate the energy levels of electrons without any problems, changing their bite state.

The principle of operation of a new type of drives does not change, in it, as before, use magnetism to record status 0 or 1. However, tens of thousands of atoms are used in the existing data storage technologies for one bit. The new approach will reduce the power consumption of drives in the process of work, as well as increase the volume or significantly reduce their size.
