Spin-density functional study of the organic polymer dimethylaminopyrrole: A realization of the organic periodic Anderson model
arXiv:0907.2477 · doi:10.1103/PhysRevB.82.235127
Abstract
While the periodic Anderson model (PAM) has been recognized as a good model for various heavy f-electron systems, here we design a purely organic polymer whose low-energy physics can be captured by PAM. By means of the spin density functional calculation, we show that polymer of dimethylaminopyrrole is a candidate, where its ground state can indeed be magnetic depending on the doping. We discuss the factors favoring ferromagnetic ground state.
