Superconducting properties of quasi-two-dimensional organic metals

The nature of the complex superconducting state in organic charge-transfer salts is a topic of continuous controversial debate and far from being unequivocally clarified. This paper presents some recent perspectives on the rich variety of the .physical aspects of the superconductivity in quasi-two-dimensional 2D organic superconductors. After a short review of the up to date not yet conclusive experimental situation, which is interpreted either by the usual BCS theory or as an indication for unconventional superconductivity, some recent results on the magnetic phase diagram, on fluctuation effects, on th
