“…However, Abrikosov 34 pointed out the possibility of spin-triplet pairing based on the fact that T c is very sensitive to the existence of non-magnetic defects. 20,21,35,36 More recently, Joo et al 22,23 have shown that the sensitivity of T c to non-magnetic impurities (ReO 4 ) in (TMTSF) 2 ClO 4 is precisely what is expected from the T c reduction formula 37,38 for unconventional pairing. Generally, in a superconducting state that satisfies the condition…”

A review is given on theoretical studies concerning the pairing symmetry in organic superconductors. In particular, we focus on (TMTSF)2X and κ-(BEDT-TTF)2X, in which the pairing symmetry has been extensively studied both experimentally and theoretically. Possibilities of various pairing symmetry candidates and their possible microscopic origin are discussed. Also some tests for determining the actual pairing symmtery are surveyed.

“…This charge localization manifests below a temperature, T ρ [66], higher than the onset temperature of the critical growth of the SP fluctuations. In the x = 30% salt the 2k F fluctuations detected below the spin-charge separation temperature T ρ [67] are thus the structural fingerprint of an incipient SP instability which fully diverges in (TMTTF) 2 PF 6 .…”

Abstract:We review structural aspects of the Bechgaard and Fabre salts in relationship with their electronic, magnetic and superconducting properties. We emphasize the role of bond and charge modulations of the quarter filled organic stack in the various instabilities and ground states exhibited by these salts. A special consideration is also devoted to the influence of anions and methyl groups in these processes. In particular we point out the importance of the anions in achieving the inter-stack coupling by either direct or indirect (via the polarization of the methyl group cavities) interactions with the donors. In this framework we discuss the role of anions and methyl group disorders in the inhibition of the divergence of the high temperature bond order wave instability of the Bechgaard salts. We analyze the modulation in the magnetic ground states by considering explicitly the coupling of the magnetization with structural degrees of freedom. We consider the role of the anions and methyl groups in stabilizing the charge ordering pattern in the Fabre salts. We also discuss the spin-Peierls transition of the Fabre salts in relation with the charge ordering transition and the adiabaticity of the phonon field. We review the anion ordering transitions by considering more particularly the influence of the ordering process on the electronic structure and on the ground states which results. In this framework we show that the texture of the anion ordered structure has direct consequences on the superconducting properties of (TMTSF) 2 ClO 4 . Finally we conclude on the essential implication of the structural degrees of freedom on the generic phase diagram of the Bechgaard and Fabre salts. OPEN ACCESSCrystals 2012, 2 467
