New Journal of Physics 8, pp 82 (2006)Based on the static polaron Su-Schrieffer-Heeger model and the nonequilibrium Green's function formalism, we investigate the negative differential resistance (NDR) effect in organic spin-valve systems at low temperature and interpret it with a self-doping picture. A giant negative magnetoresistance exceeding 300 percent is theoretically predicted as the results of the NDR effects.
