Sublimated Decoupling of the Vortex Lattice in Extremely Type-ii Layered Superconductors

چکیده

The question of whether layer decoupling and vortex-lattice melting occur separately or not in the mixed phase of extremely type-II layered superconductors is studied through a partial duality analysis of the layered XY model with uniform frustration. We find that both transitions occur simultaneously if a sufficient degree of both layer anisotropy and of substrate pinning exists. PACS Indices: 74.60.Ge, 74.60.-w, 74.60.Ec, 74.25.Dw

Nature of Decoupling in the Mixed Phase of Extremely Type-ii Layered Superconductors

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 secondorder 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-te...

THEORY FOR DECOUPLING IN HIGH-Tc SUPERCONDUCTORS FROM AN ANALYSIS OF THE LAYERED XY MODEL WITH FRUSTRATION

The nature of decoupling in the mixed phase of extremely type-II layered superconductors is studied theoretically through a duality transformation of the layered XY model with frustration. In the limit of weak coupling, we generally find that the Josephson effect is absent if and only if the phase correlations within isolated layers are short range. In the case specific to uniform frustration, ...

Theory for Decoupling in the Mixed Phase of Extremely Type-ii Layered Superconductors

The mixed phase of extremely type-II layered superconductors in perpendicular magnetic field is studied theoretically via the layered XY model with uniform frustration. A partial duality analysis is carried out in the weak-coupling limit. It consistently accounts for both intra-layer (pancake) and inter-layer (Josephson) vortex excitations. The main conclusion reached is that dislocations of th...
