| Abstract: | The new ambient pressure organic superconductor based on unsymmetrical donor, ethylenedithiotetrathiafulvalene, and the iodomercurate anion, (EDT-TTF)4Hg3−δI8, δ0.1–0.2, with Tc=8.1 K has been synthesized. Transport and magnetic properties have been investigated. Upper critical fields have been studied under parallel and perpendicular magnetic fields up to 17 T in the temperature region down to 1.3 K. The data show that upper critical fields are within the paramagnetic limit in all directions. The coherence lengths indicate that (EDT-TTF)4Hg3−δI8, δ0.1–0.2, is a quasi-two-dimensional organic superconductor. |
