Theory of ferromagnetism in carbon foam

An explanation is proposed for spontaneous magnetism in the material, carbon nanofoam, in terms of random ferrimagnetism. Wherever a carbon nanotube branches out, an electron trap is created at the junction. Electrons occupying neighboring junctions align their spins antiparallel. Given that there are more sites on sublattice A than on the interpenetrating sublattice B, the net result is M=m(o)parallel to N-A-N(B)parallel to not equal 0. Ultimately, some excess charge (and concomitant magnetism) is expected to dissipate into the atmosphere.
