Abstract

(BEDT-TTF)₃Cl₂.2H₂O has been synthesised by a direct method and its electrical transport properties as a function of pressure and temperature reinvestigated. At 295K, the resistivity decreases by 65% to near saturation, on application of 16 kbar pressure. At ambient pressure, the material shows a smooth localisation of carriers spanning about 60K; the slope in a lnR vs 1/T plot changes with temperature and maximises at about 100K. On increasing pressure, the temperature of minimum resistivity decreases. Between 10 and 13 kbar a transition to lower resistance is observed, which is associated to partial superconductivity (i.e : zero resistance is not attained). At higher pressures, this transition is complete (i.e : zero resistance). We believe that both localisation and superconductivity coexist in the state between 10 and 14 kbar.
