Abstract
We propose a new scattering mechanism for the resistivity based on electron low-lying collective mode (spin wave like) collisions. This scattering is particularly efficient in TTF-TCNQ as magnetic ordering is nearly achieved in this material under ambient conditions (U/4 t∥ ~ 1). Also it provides a theoretical quasi-linear temperature dependence at constant b-axis together with the essential connection noticed between conductivity and magnetism in TTF-TCNQ and all derivative compounds
