摘要
The magnetic properties of conducting polymers are investigated within a one-dimensional periodic Anderson model in which effects stemming from electron-lattice intercations are explicitly included. The effective Hamiltonian derived via bosonization exhibits ferromagnetic ground state in the intermediate coupling regime. For these ferromagnetic polymers, the results show that phononic contributions have insignificant effect on ferromagnetism.
