Abstract
The pressure dependence of the static susceptibility of the α and β phases of (BEDT-TTF)2I3 and of (TMTSF)2X for X = ClO4−, PF6−, ReO4− was measured using a Faraday balance up to a pressure of 10 kbar. The fractional pressure dependence δ 1nξs/δP is -2.0%/kbar and −3.3%/kbar for the α- and β-(BEDT-TTF)2I3 respectively and it is temperature independent. For (TMTSF)2X δ1nξs/δP is about −3.0%/kbar at room temperature and increases to −4.8%/kbar on cooling. Both the magnitude and temperature dependence of the fractional pressure dependence in those two families are in contrast with the behaviour in TTF-TCNQ, where the magnitude is −8.%/kbar and decreases with decreasing temperature.
