摘要	The ground state properties and spin-density wave of polymeric Hubbard chains are studied by means of the mean-field theory. It is shown that topological structure of the chain possesses a flat-band structure of the energy band. Our analysis shows that the on- site Coulomb repulsion of electrons in the chain leads to the coexistence of ferromagnetic and antiferromagnetic order, i,e., the ferrimagnetic order. Away from half filling, the system displays magnetic phase separation. Possible experimental realizations are suggested.
