The resistivity along the conducting chains, pxx, and the Hall resistivity pxy are investigated as a function of the electric field in the magnetic-field-induced spin-density wave (FISDW) states of (TMTSF)2PF6 under hydrostatic pressure. Both resistivities decrease with increasing electric field above the same well-defined threshold electric field in the order of 100 µV/cm. We interpret the nonlinearity by the depinning and sliding of the FISDW. The nonlinearity in pxy is much stronger than in pxx what we attribute to an unusually strong coupling between the FISDW and single-particle excitations.
