摘要
A new kind of organic polymer ferromagnet based on polaron is proposed.In this kind of polymer,there are no organic free-radicals,which are rather reactive and unstable,instead spins are provided by polarons.Allowing for full lattice relaxation,the system is studied self-consistently by Peierls-Hubbard model.The formation energies of polarons are calculated.The possible ferromagnetism in polymers of this type is demonstrated.
