Direct observation of the flux-line vortex glass phase in a type II superconductor.

چکیده
The order of the vortex state in La1.9Sr0.1CuO4 is probed using muon-spin rotation and small-angle neutron scattering. A transition from a Bragg glass to a vortex glass is observed, where the latter is composed of disordered vortex lines. In the vicinity of the transition the microscopic behavior reflects a delicate interplay of thermally induced and pinning-induced disorder.

The Ginzburg-Landau Theory of Type II superconductors in magnetic field
Thermodynamics of type II superconductors in electromagnetic field based on the Ginzburg Landau theory is presented. The Abrikosov flux lattice solution is derived using an expansion in a parameter characterizing the ”distance” to the superconductor normal phase transition line. The expansion allows a systematic improvement of the solution. The phase diagram of the vortex matter in magnetic fie...
متن کاملEntanglement transition of elastic lines in a strongly disordered environment
– We investigate by exact optimization the geometrical properties of threedimensional elastic line systems with point disorder and hard-core repulsion. The line ’forests’ become entangled due to increasing line wandering as the system height is increased, at fixed line density. There is a transition height at which a cluster of pairwise entangled lines spans the system, transverse to average li...
متن کاملMeasurement of the Vortex Pair Interaction Potential in a Type-II Superconductor
We describe the first direct measurement of the pair interaction potential for magnetic flux lines in a Type-II superconductor. Our approach relies on quantitative analysis of Lorentz microscope images of vortices creeping through a superconducting thin film. Time-resolved vortex distributions imaged in this way reflect both the vortices’ mutual interaction and also the influence of random pinn...
متن کاملDisorder driven melting of the vortex line lattice.
The 3D XY model with random in-plane couplings is simulated to model the phase diagram of a disordered type II superconductor as a function of temperature T and randomness strength p for fixed applied magnetic field. As p increases to a critical p(c), the first order vortex lattice melting line turns parallel to the T axis, continuing down to low temperatures, rather than ending at a critical p...
متن کاملUnified phase diagram for the three-dimensional XY model of a point-disordered type-II superconductor
We carry out extensive Monte Carlo simulations of the three-dimensional uniformly frustrated XY model with uncorrelated randomly perturbed couplings, as a model for the equilibrium behavior of an extreme type-II superconductor with quenched uncorrelated random point vortex pinning, in the presence of a uniform applied magnetic field. We map out the resulting phase diagram as a function of tempe...
