Abstract : Conducting polymers holding pentagon cells are
analyzed based on a technique which uses positive
semidefinite operator properties, and it is shown that these
systems can provide ferromagnetism even if do not contain
magnetic atoms at all. The mechanism leading to the
ordered phase is related to the presence of flat bands in the
band structure of the system.
