“…In KOs 2 O 6 it was explained in terms of orbital limiting mechanism, due to missing spatial inversion symmetry [66]. In organic superconductor κ-(BEDT-TTF) 2 Cu[N(CN) 2 ]Br, T -linear dependence was found in magnetic fields parallel to the two-dimensional plane [67,68]. Interestingly, here the behavior at ambient pressure closely follows a square root dependence as expected for paramagnetic Pauli limiting [69], while with pressure this dependence becomes close to T -linear [67,68].…”

Interestingly, here the behavior at ambient pressure closely follows a square root dependence as expected for paramagnetic Pauli limiting [172], while with pressure this dependence becomes close to T -linear [170,171]. A similar trend is found in other organic superconductors [173], and possible relation of T -linear dependence to the formation of inhomogeneous Fulde-Ferelle-Larkin-Ovchinnikov state [174] was suggested by the experiments on samples with varying disorder [175].…”
