在发现第一个有机超导体四十年后，这些材料中超导状态的性质仍然没有被完全理解。本文概述了准一维和准二维有机电荷转移盐的历史发展和当前知识。因此，我重点研究了基于供体分子四甲基四硫代四硫代戊烯（TMTSF）和二乙烯二硫代四硫代戊烯（BEDT-TTF，简称ET）的原型材料。基于后者分子的二维有机超导体被发现在高磁场和低温下表现出富尔德-费雷尔-拉金-奥夫奇尼科夫（FFLO）态。热力学和核磁共振数据有力地证明了这种调阶参数的FFLO状态的存在。
Forty years after the discovery of the first organic superconductor, the nature of the superconducting state in these materials is still not fully understood. Here, I present an overview on the historical developments and current knowledge on this topic for the quasi-one- and quasi-two-dimensional (2D) organic charge-transfer salts. Thereby, I focus on the prototype materials based on the donor molecules tetramethyltetraselenafulvalene (TMTSF) and bisethylenedithio-tetrathiafulvalene (BEDT-TTF or ET for short). 2D organic superconductors based on the latter molecule are found to show Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) states at high magnetic fields and low temperatures. Thermodynamic and nuclear magnetic resonance data give robust evidence for the existence of this FFLO state with modulated order parameter.
