Graphene is claimed to be an ideal material for spintronics due to its small spin-orbit interaction and the near absence of nuclear magnetic moments in carbon ( as well as a weak hyperfine interaction ).

It arises from a subtle interplay of electronic and nuclear spins : at ultra-low temperatures and corresponding excitation energies, the half-integer total spin of the electronic shell and half-integer total spin of the nucleus are coupled by a very weak hyperfine interaction.

The RKKY interaction was originally proposed by M . A . Ruderman and Charles Kittel of the University of California, Berkeley, as a means of explaining unusually broad hyperfine interaction, and this conduction electron then interacts with another nuclear spin, thus creating a correlation energy between the two nuclear spins . ( Alternatively, instead of nuclear spins coupling to conduction spins through the hyperfine interaction, another scenario is for inner electron spins to couple to conduction spins through the exchange interaction . ) The theory is based on Bloch wavefunctions and is therefore only applicable to crystalline systems.
