摘要：

The superconducting transition of the organic compounds kappa-(BEDT-TTF)2X is studied by resistive measurement in a magnetic field up to 10 T applied normal to the conducting plane. For the salts with X = Cu[N(CN)2]Br and X = CuCN[N(CN)2] the transition shows fan-shaped broadening caused by superconductivity fluctuation. For the X = Cu(NCS)2 salt the resistivity shows a peak in the transition region in a magnetic field below 4 T. This phenomenon is suppressed in defect-reduced samples for intralayer conduction. We discuss this peak in relation to the thermal fluctuation on the Josephson junction structures in this salt.
