Description

We microscopically study the effect of the magnetic field on the pairing state competition between spin singlet, spin triplet, and the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in a model for quasi-one-dimensional organic conductors (TMTSF)2X. We obtain phase diagram in the temperature-magnetic field space. We show that consecutive pairing transition from singlet pairing to FFLO state and further to Sz=1 triplet pairing can take place upon increasing the magnetic field when 2kF charge fluctuations coexist with 2kF spin fluctuations.
