Nature of Decoupling in the Mixed Phase of Extremely Type-II Layered Superconductors
arXiv:cond-mat/9906199 · doi:10.1209/epl/i2001-00324-1
Abstract
The uniformly frustrated layered XY model is analyzed in its Villain form. A decouple pancake vortex liquid phase is identified. It is bounded by both first-order and second-order decoupling lines in the magnetic field versus temperature plane. These transitions, respectively, can account for the flux-lattice melting and for the flux-lattice depinning observed in the mixed phase of clean high-temperature superconductors.
