The Vortex Lattice in Ginzburg-Landau Superconductors

نویسنده

  • Ernst Helmut Brandt
چکیده

Abrikosov’s solution of the linearized Ginzburg-Landau theory describing a periodic lattice of vortex lines in type-II superconductors at large inductions, is generalized to non-periodic vortex arrangements, e.g., to lattices with a vacancy surrounded by relaxing vortices and to periodically distorted lattices that are needed in the nonlocal theory of elasticity of the vortex lattice. Generalizations to lower magnetic inductions and to threedimensional arrangements of curved vortex lines are also given. Finally, it is shown how the periodic vortex lattice can be computed for bulk superconductors and for thick and thin films in a perpendicular field for all inductions B̄ and Ginzburg-Landau parameters κ.

Muon Spin Rotation and the Vortex Lattice in Superconductors

The magnetic field probability P (B) is calculated from Ginzburg-Landau theory for various lattices of vortex lines in type-II superconductors: Ideal triangular lattices, lattices with various shear strains and with a super lattice of vacancies, and lattices of short vortices in films whose magnetic field “mushrooms” near the surface.

Vortex lattice pinning in high-temperature superconductors

Vortex matter in high temperature superconductors has many peculiar properties such as melting of the vortex lattice, creation of new vortex-liquid phases etc. These effects are not seen in conventional superconductors. This is mainly due to the fact that HTc compounds are strongly type two superconductors with Ginzburg-Landau ratio up to ~110 that makes thermal and quantum fluctuations more pr...

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...

On the Energy of Superconductors in Large and Small Domains

We study the Ginzburg-Landau energy functional for superconductors in an applied magnetic field. We focus on asymptotically large or small domains and establish the asymptotic behavior of the energy as a function of the Ginzburg-Landau parameter, applied magnetic field and domain size. For a large class of domain sizes, we calculate the critical field strength where vortex nucleation becomes en...

Stochastic dynamics of Ginzburg-Landau vortices in superconductors

The phenomenological Ginzburg-Landau model for lowtemperature superconductivity has received much attention. However, it is not applicable to physical contexts that do not take into account factors such as material defects or thermal fluctuations. Thus, existing studies of the stability, dynamics, interactions, and other properties of the vortex state do not necessarily carry over to situations...
