Abstract
The effects of temperature, pressure and magnetic field on the electri cal transport of single crystal of(ET)(3)Cl-2.2H(2)O are reported. Inc reasing pressure gradually reduces the ordering temperature of a charg e density wave ground state from similar to 160 K at 1 bar to 6 K at 1 0.2 kbar. A superconducting state with T-c>4 K is stabilised between 1 0.2 kbar and 13.5 kbar. Above 12.5 kbar, the observation of Shubnikov- de Haas oscillations allows the pressure dependences of the area of a closed Fermi surface pocket and the associated carrier effective mass to be deduced.
