Commensurate Spin-Density Wave State in (TMTTF) 2 Br: Single-Particle and Collective Charge Dynamics. Tomić, S., Biškup, N., Babic, S., D., & Maki, K. Europhysics Letters (EPL), 26(4):295-301, 1994. Website abstract bibtex We report the first transport characterization of a unique commensurate spin-density wave state of the organic charge insulator (TMTTF)2 Br. An additional anomaly in d.c. resistivity is observed at 22 K, above the SDW transition temperature Tc = 12.5 K. Non-Ohmic current-voltage characteristics with sharp threshold fields of the order of 1-10 V/cm are observed in the SDW state. The threshold field is thermally activated at low temperatures and increases again close to Tc. Properties of the low-frequency dielectric response and the sliding state indicate a novel charge dynamics associated with this SDW condensate.
