Flux lattice makes a hesitant breakaway
Article Abstract:
The breakaway motion of a viscoelastic medium against the random pinning forces in a type II NbSe2 superconductor occurs in two stages. In the first stage, no appreciable voltage is observed for the elastic response of the vortex lattice at small currents and the longitudinal correlation length remains the same. In the second stage, with detectable vortex motion through high current, the correlation length reduces by nearly 20% and the vortex lattice becomes slightly disordered though recovery of correlation length occurs as soon as uniform flow takes place. A vortex configuration with lower free energy is produced through a low temperature, dynamic annealing procedure.

Has the fat lady sung?
Article Abstract:
The magnetic vortex lattice melts into vortex liquid that makes the superconducting state inimical to magnetic fields for the generation of responses that minimize the magnetic flux in its interior. The equilibrium having the first critical field equal to the second, completely destroys the first class of superconductors. The pathological behavior of the magnetic vortices is due to solid-state lattice formation by the low temperature type-II superconductors. The high temperature materials experience thermal fluctuations that cause the ordered vortex lattice to melt.

Magnetic-field-induced superconductivity in a two-dimensional organic conductor
Article Abstract:
Research is presented concerning the mechanisms by which the superconducting state of a superconductor can be eliminated through the use of a strong magnetic field. The orbital and Zeeman effects are discussed.
