Anisotropic Superconductivity of Quasi-One-Dimensional Electrons in Magnetic Field
arXiv:cond-mat/9608068 · doi:10.1143/JPSJ.65.3283
Abstract
We study theoretically the transition temperature of a quasi-one-dimensional anisotropic superconductor in a magnetic field, which is thought to be realized in organic conductors,(TMTSF)2X. In the weak field limit,-dH_c2/dT for the anisotropic singlet is shown to be \sqrt{3} times larger than that for the anisotropic triplet in the case of attractive interaction of electrons at nearest-sites along c axis and magnetic field along the b axis. In the strong field region the transition temperature for spin-triplet is restored to zero field critical temperature while the anisotropic spin-singlet is suppressed by the Zeeman effect.
