Abstract

In this paper, we report transport measurements of the interlayer magnetoresistance with field, H, parallel to the current, J, in the organic superconductor κ-(bis(ethylenedithio)-tetrathiafulvalene (ET))₂I₃. The isothermal magnetoresistance R(H) displays a peak as a function of field for 1 > T/T_c > 0.4. At lower temperatures T/T_c < 0.4, R(H) increases monotonically with field. Comparison with several other organic superconductors suggests the interlayer magnetoresistance peak is intrinsic to layered systems. Quantitative analysis shows that the magnetoresistance at small field can be fitted to the stacked Josephson-junction model with the normalized coupling energy proportional to (1 - T/T_c)^3/2/H.
