Magnetic nanographite
Hydrogenated nanographite can display spontaneous magnetism. Recently we
proposed that hydrogenation of nanographite is able to induce finite
magnetization. We have performed theoretical investigation of a graphene ribbon
in which each carbon is bonded to two hydrogen atoms at one edge and to a
single hydrogen atom at another edge. Application of the local-spin-density
approximation to the calculation of the electronic band-structure of the ribbon
shows appearance of a spin-polarized flat band at the Fermi energy. Producing
different numbers of mono-hydrogenated carbons and di-hydrogenated carbons can
create magnetic moments in nanographite.Comment: 4 pages, 3 Postscript figures, uses revtex4.cls, submitted to Phys.
