Abstract
Motivated by a striking observation of a Fulde-Ferell-Larkin-Ovchinnikov (FFLO) vortex state in the heavy fermion material CeCoIn5 in fields perpendicular to the superconducting planes (H‖c), superconducting phase diagrams including an FFLO state of uniaxially anisotropic superconductors are systematically studied. In the ballistic limit with no quasiparticle (QP) relaxation, the high-field superconducting state in H‖c and in the low temperature limit should be not the FFLO state modulating along H, appearing in CeCoIn5, but a different vortex state with a modulation perpendicular to the field. It is argued that an enhancement near Hc2(0) of the QP relaxation rate, presumably originating from a nonsuperconducting quantum critical fluctuation, in this material is the origin of the absence of the latter modulated state and of the strange H‖c phase diagram in which the FFLO state is apparently different from that in H⊥c.
