Abstract
A patterned magnetic graphene made from the steps of transferring or growing a graphene film on a substrate, functionalizing the graphene film, hydrogenating the graphene film and forming fully hydrogenated graphene, manipulating the extent of the hydrogen content by using an electron beam from a scanning electron microscope to selectively remove hydrogen, wherein the step of selectively removing hydrogen occurs under a vacuum, and forming areas of magnetic graphene and non-magnetic graphene. A ferromagnetic graphene film comprising film that has a thickness of less than two atom layers thick.
