Abstract
In quasi 2D , extremely type-II superconductors, such as the organic charge transfer salts (ET)2 X, the metal to superconductor transition at high magnetic fields is broadened dramatically by superconducting (SC) fluctuations. At temperatures well below T c2(H) amplitude fluctuations of the SC order parameter are strongly suppressed, and low lying phase fluctuations associated with sliding motions of Bragg chains along the principal crystallographic axis in the vortex lattice, lead to discontinuous ’melting’ of the Abrikosov lattice into a nematic-like liquid crystal. The complete melting into an isotropic vortex liquid is shown to occur only near T c2(H), since the energy cost of the fluctuations which break the chain structure is of the order of the SC condensation energy. The damping of the de Haas-van Alphen oscillations in the crossover region is stronger than predicted by the Lifshitz-Kosevich formula. A simple model of independent Landau orbitale with strong SC amplitude fluctuations accounts well for this additional damping. It is predicted that below the freezing point the additional damping will be weaken significantly due to the establishment of long range phase coherence.
