The rare coexistence of ferromagnetism and electrical conductivity is observed in the reduced graphene oxide–metal oxide hybrids rGO-Co, rGO-Ni, and rGO-Fe. This is seen using chemical reduction with hydrazine or ultraviolet photoirradiation of the graphene oxide–metal complexes GO-Co, GO-Ni, and GO-Fe.
