Hidden reentrant superconducting phase in a magnetic field in (TMTSF)2ClO4
Abstract
We suggest explanation of the high upper critical magnetic field, perpendicular to conducting chains and parallel to conducting layers H {/c2 b' } ≃ 6 T, experimentally observed in the organic superconductor (TMTSF)2ClO4. In particular, we show that H {/c2 b' } can be higher than both the quasiclassical upper critical field and Clogston-Chandrasekhar paramagnetic limit in a singlet quasi-one-dimensional superconductor. We predict the coexistence of the hidden Reentrant and Larkin-Ovchinnikov-Fulde-Ferrell phases in a magnetic field. Our results are compared to the recent experimental data and shown to be in a good agreement with the experiments.
