“…3,4,5 A number of layered organic superconductors have been suggested as candidates for FFLO phases. 6,7,8,9,10,11 However, recent interest has focussed on the heavyfermion material CeCoIn 5 . 12 This material has quasitwo-dimensional (2D) metallic planes, and shows evidence of unconventional, d-wave, superconductivity 13,14 with a transition temperature of T c = 2.3 K. The quasi-2D tetragonal crystal structure consists of alternating of CeIn 3 and CoIn 2 .…”

Experimental evidence suggests that the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state may be realized in the unconventional, heavy-fermion superconductor CeCoIn5. We present a self-consistent calculation of the field versus temperature phase diagram and order parameter structures for the FFLO states of quasi-two-dimensional d-wave superconductors. We calculate the spatially nonuniform order parameter, free energy density, and local density of states for magnetic fields parallel to the superconducting planes. We predict that the lower critical magnetic field transition between the spatially uniform and nonuniform FFLO state is second order. We discuss the signatures of the nonuniform FFLO state which should be observable in scanning tunneling microscopy measurements of the local density of states.

“…Compared with the ET salts, the BETS salts have large sideby-side transfer interactions and thus less weak electron correlations for the -phase. 608 The BETS superconductors, especially with !- 609,610 or -type packings, [611][612][613] have been studied in terms of the competition of magnetic ordering and superconductivity, and will be briefly reviewed in section 4.7.…”

“…However, Konoike et al have reported resistive [8] and magnetic torque [11] data suggesting that the two transitions, while being close to each other, do not exactly coincide, at least at the lowest temperatures. A possible explanation is that at low temperatures the AF state undergoes a spin-flop transition before being completely destroyed by magnetic field.…”

“…In Fig. 2 we summarize the data on the T -dependent AF and (low-field) SC critical fields from Konoike et al [8] (hollow symbols) along with those determined in this work (solid symbols); we now consider the zero-pressure data. One can see that the very steep, ≈ 7 T/K, initial slope of the SC phase boundary near T c (B = 0) is interrupted exactly when it meets the AF phase boundary.…”

The mutual influence of the conduction electron system provided by organic donor layers and magnetic system localized in insulating layers of the molecular charge transfer salt κ-(BETS)2FeBr4 has been studied. It is demonstrated that besides the high-field re-entrant superconducting state, the interaction between the two systems plays important role for the low-field superconductivity. The coupling of normal-state charge carriers to the magnetic system is reflected in magnetic quantum oscillations and can be evaluated based on the angle-dependent beating behaviour of the oscillations. On the other hand, the conduction electrons have their impact on the magnetic system, which is revealed through the pressure-induced changes of the magnetic phase diagram of the material.
