The longitudinal magnetoresistance of a two-dimensional superconductor, β' Et 2Me 2P[Pd(dmit) 2] 2 (dmit = C 3S 5 2- under hydrostatic pressure was measured at low temperatures with the field applied perpendicular to the conducting layers. At 0.58 GPa, the field-dependent isothermal interlayer resistance R ⊥(H) exhibited a peak below the superconducting transition temperature T C. This peak effect can be explained by a model of resistively-shunted Josephson-Junctions. The peak is strongly suppressed at a higher pressure, 0.71 GPa.
