This magnetic state opens fascinating perspectives on the use of these pure-carbon magnets in technology. (2020-05-11)

Double layer of graphene helps to control spin currents
In order to make transistors that operate using the spin of electrons, rather than their charge, it is necessary to find a way of switching spin currents on and off.
