Superconductivity at Normal Pressures of Some Organic Metals of (BEDT-TTF)-I System

Abstract

Abstract The discovery by K. Bechgaard, D. Jerome et al.1 in 1980 of the first organic superconductor, (TMTSF)2 PF6, was, in some sence, the final step of a long way to organic superconductivity begun about ten years earliler. Although the existence of a number of organic metals was well established already by 1975, till 1978 there was no assureance that organic superconductors may exist. Because all first organic metals were of 1d type, and their metallic properties did not conserve at low enough temperatures.
