Low Temperature Thermodynamical Properties of the Organic Chain Conductor (TMTTF)2Br

Pressure-temperature phase diagrams of several (TMTTF)2X compounds : stabilisation of a highly conducting metallic state under pressure in (TMTTF)2Br

2014 Needle axis resistivity measurements on several TMTTF (tetramethyltetrathiafulvalene) salts of the form (TMTTF)2X, with X = Br, ClO4, PF6, are presented for pressures up to 32 kbar. The pressure-temperature phase diagrams of all three materials are similar with the stabilization under pressure of a metallic state to low temperatures (~ 20 K), below which there is a well defined metal-insul...

1H-NMR relaxation measurements in the organic conductors : (TMTTF)2Br and (TMTTF)2PF6

Dielectric Response of Charge Induced Correlated State in the Quasi-one-dimensional Conductor (tmttf) 2 Pf 6 Typeset Using Revt E X 1

Conductivity and permittivity of the quasi-one-dimensionsional organic transfer salt (TMTTF)2PF6 have been measured at low frequencies (10 3 − 10 Hz) between room temperature down to below the temperature of transition into the spin-Peierls state. We interpret the huge real part of the dielectric permittivity (up to 10) in the localized state as the realization in this compound of a charge orde...
