Non-Ohmic Electrical Transport in the Spin-Density-Wave State of Tetramethyltetraselenafulvalinium Nitrate, (TMTSF)2NO3
Résumé
Electric-field-dependent measurements are reported in the spin-density-wave state of the organic conductor (TMTSF)2NO3. Nonlinearity appears in the longitudinal conductivity above a finite threshold field of about 40 mV/cm. No temperature dependence is detectable up to at least half of the transition temperature. The excess conductivity is smaller in samples with a lower resistance ratio. The sliding spin-density-wave mode might be responsible for the observed electric-field-dependent response.
