Interacting Electrons in Quasi-One-Dimensional Organic Superconductors

“…Furthermore, in support to an early suggestion [143], the band structure parameters of (TMTSF) 2 ClO 4 can explain the values and the anisotropies of the critical fields assuming the existence of nodes of the superconducting order parameter [142]. These results imply that critical fields values calculated without any contribution from the spin-orbit coupling can overcome the Pauli limit at low temperature by factors of two or more [144,145].…”

“…Early data in (TMTSF) 2 ClO 4 [141] are not in contradiction with the picture of singlet pairing but no data were given below 0.5K, the temperature domain where it would be most rewarding to see how H c2 compares with the Pauli limit, when H is perfectly aligned along the a and b axes. This study has been revisited quite recently in perfectly aligned magnetic fields down to 0.2K [142].…”

“…When the magnetic field is oriented along the intermediate b-axis violations of the Pauli limitation have been claimed in (TMTSF) 2 PF 6 [144] and recently in (TMTSF) 2 ClO 4 superconductors [145]. However, it must be kept in mind that in all these experiments under transverse magnetic field along the b axis, the electronic structure is profoundly affected by the application of the field which tends to localize the electrons as shown by the normal state crossing over from a metallic to an insulating state when investigated with a current along c * [142]. Furthermore it is still unclear whether the superconducting phase remains uniform under very strong transverse field [173,174].…”
