The magnetic properties of graphene oxide have been investigated using spin-polarized density functional theory. A series of structures with an epoxy-pair chain at various positions on zigzag graphene nanoribbons is considered. The results show that this kind of graphene oxide is ferromagnetic at the ground state, providing great promise in the field of spintronics. In comparison with zigzag graphene nanoribbons of the same width, this graphene oxide is metallic and its spin density distribution is modified by epoxy pairs at different locations, thus rendering some fundamental insights into graphene-based materials.
