EFFECT OF MAGNETIC-FIELD ON THE GROUND-STATE OF 2-D ORGANIC SUPERCONDUCTOR KAPPA-(ET)2CU[N(CN)2]CL

We report the results of resistivity measurements carried out on singl e crystals of kappa-(ET)2Cu-[CN)2]Cl in an applied magnetic fields to 10 T. Hydrostatic pressures have been used to stabilize the metallic s tate and superconductivity. In a fields to 10 T applied parallel to th e highly conducting ac plane, and in a low fields normal to the plane the field effect on the superconducting transition is observed to be s imilar to other layered superconductors. However, the application of a higher fields normal to the a-c plane causes the resistivity to exhib it sharp metal/superconductor to insulator transition.
