Abstract
The authors show that it is possible to suppress the ambient-pressure metallic phase in (2,5 DM-DCNQI)2Cu by applying a pressure-even one as low as 100 bar. On increasing the pressure up to 8.5 kbar, the metal-insulator transition temperature increases and its strong first-order character becomes weaker, whereas the activation energy stays constant. In addition, a re-entrance of the metallic phase is observed at very low temperatures up to pressures of about 300 bar.Keywords
