Abstract

We report the electric-field-dependent conductivity above a finite threshold field (E_T) in the spin-density wave (SDW) state of the organic conductors (TMTSF)₂X, X=NO₃, PF₆. E_T is temperature independent below half of the transition temperature (T_C) and varies close to T_C. For most pristine PF₆ samples E_T increases substantially towards T_C, while for irradiated samples this rise becomes much smaller. The value of E_T increases linearly with defect concentration and the magnetude of field-dependent conductivity strongly decreases. We discuss our results in the framework of the Maki's theory for the sliding SDW becoming depinned above a finite electric field and being responsible for the electric-field-dependent response.
