Emergence of ferromagnetism in conducting polymers in the presence of lattice vibrations

Abstract

The emergence of ferromagnetism in conducting polymers is well known, however, the influence of lattice vibrations has not been analyzed yet. Hereafter, we fill this gap by studying the common effect of strong correlations and lattice vibrations in hole doped conjugated polymers. The results underline that away from system half-filling, the lattice vibrations have negligible effect on the studied ordered phase.
