One of the great objectives of physics is the elaboration of memories based on simple atoms. So far, the 'superparamagnetic limit' has been an obstacle that seems to have been overcome by IBM researchers. In a thin non-magnetic layer, iron atoms (or manganese atoms) have been placed that have made the magnetic moment of the atoms have a certain direction. This advance, for the moment, will not serve to make the memories more compact, since they have worked at a temperature of 0.5 Kelvin.
