I. Smirani et al., Realization and characterization of solid-solid (BEDT-TTF)/iodine C-T composites exhibiting metallic conductivity down to 0.34 K., SYNTH METAL, 102(1-3), 1999, pp. 1259-1260
It is shown that the organic composite obtained by a direct solid-solid C-T
reaction between BEDT-TTF and iodine is metallic from 300 to 0.34 K. There
is also a clear manifestation of superconductivity below 5 K, which is con
firmed by the particular dependence of the electrical resistivity on magnet
ic field, up to 30 kG.
