Magnetic Studies of Tetrathiofulvalinium Tetracyanoquinodimethanide (TTF-TCNQ)

Phase diagram of the correlated quarter-filled-band organic salt series (o-DMTTF)2X(Foury-Leylekian1, Auban-Sensier2, Coulon3 et al. 2011Phys. Rev. B

“…58 The situation is different in "two chains compounds" like TTF-TCNQ when the single observed ESR line results of a hybridation between the two kinds of chains. In this latter case, the temperature dependence of the ESR linewidth mimics the one found for the electrical conductivity 59 (for a review about ESR in organic conductors, see, for example, Ref. 60).…”

Synthesis and characterization of tetrathiafulvalene charge transfer compounds with copper halides

“…This is somewhat larger than that of TTF*TCNQ (-6G) [22] and similar to that of TTF.SeCN (-15G) [23]. Line widths of five to fifteen gauss are attributed to spin-orbit interaction of sulfur in TTF columnar chains [12].…”

Anomalous Temperature Dependence of the Magnetic Susceptibility of Quasi-One-Dimensional Metals

“…In contrast to the cases of the indirect-gap materials Ge and Si, this new feature cannot be satisfactorily explained by the recombination of electron-hole fluid. 1 The recombination of excitonic molecules, 2 on the other hand, reproduces the emission line shape and its temperature variation adequately. We believe that this represents a clear evidence for the existence of this quasiparticle in an indirect-gap material.…”
