Abstract

The discovery [1] of superconductivity in (TMTSF)2X, X=PF6, under pressure opened a very active field of organic superconductors. Subsequently Bechgaard salts with other electron acceptors X=AsF6, C104,etc.,were found superconducting [2]. They have proved to be extraordinarily rich systems showing not only superconductivity but also spin density wave (SDW) and anion orderings [3,4,5]. Among hot interests have been the dimensionality of the electronic band, the pressure dependence of the SDW states, galvano-magnetic properties, the possibility of the coexistence of the superconducting and SDW orders and the possible triplet nature of the superconductivity. In this review of the author’s work we try to get an overall consistent understanding on them on the basis of a simplified model.
