Abstract
We have investigated the transport properties of the quasi-one-dimensional (1-D) organic conductor (TMTTF) 2 AsF 6 at high pressures. A superconducting transition was observed, for the first time, at 2.38 K from a resistance measurement at 4.5 GPa. The presence of zero resistance was also confirmed at ∼2.3 K in the pressure range of 4.65≤ P ≤5 GPa. We discuss the electron correlation in (TMTTF) 2 AsF 6 based on its pressure–temperature phase diagram.Keywords
