The observation of nonlinearity in electron spin-related processes in graphene makes it easier to transport, manipulate and detect spins, as well as spin-to-charge conversion. It also allows analog operations such as amplitude modulation and spin amplification. This brings spintronics to the point where regular electronics was after the introduction of the first transistors. These results by University of Groningen physicists were published in the journal Physical Review Applied on 17 December.
