Abstract

Abstract Electrical conductivity was measured in the spin-density wave phase of (TMTSF) 2ClO 4, which is induced in zero magnetic field when ordering of ClO 4 ions is suppressed by rapid quenching. The conductivity along the one-dimensional axis increases above a threshold field, in the range of 10–40mV cm -1. The threshold field increases slightly with increasing temperature. The conductivity increase is presumably assigned to the sliding motion of the spin-density wave, as suggested by Tomic et al. for (TMTSF) 2NO 3. Significant sample dependence is observed in threshold field-temperature and conductance-field relations; important effects of the interaction between the deformable spin-density wave and pinning centers are inferred.
