Hall effect in the normal phase of the organic conductors: (TMTSF)_2ReO_4 vs. (TMTTF)_2AsF_6
We report Hall effect measurements performed in the normal phase and at ambient pressure of (TMTSF)_2ReO_4 and (more anisotropic) (TMTTF)_2AsF_6 quasi-1D organic conductors. For T>200 K, the Hall coefficient of (TMTSF)_2ReO_4 is smoothly temperature-dependent, and its value corresponds to a carrier concentration of one hole/unit cell. On the other hand, the Hall coefficient of (TMTTF)_2AsF_6 is enhanced above 220 K, and the corresponding carrier concentration is almost 100 times lower than the expected one for one hole/unit cell. Our results give evidence for the existence of a high temperature regime above 200 K in (TMTTF)_2X salts, where the 1D Luttinger liquid features appear in the transport properties.
