Organic conductors and superconductors

Salient developments of research on organic conductors and superconductors during the past 10 years are presented. A theoretical introduction treats instabilities of quasi-one-dimensional electron systems and associated precursor effects which are relevant to the experimental results on organic conductors. The characterization of quasi-one-dimensional organic conductors is described by their transport, optical and magnetic properties. The experimental investigation of the low temperature instabilities is reported under the headings; lattice instability in TTF-TCNQ and related compounds, and superconducting or antiferromagnetic instabilities in the (TMTSF)2X series.
