Structural evidence for a two-step process in the depinning of the superconducting flux-line lattice

A TYPE II superconductor in a magnetic field is penetrated by a hexagonal lattice of quantized flux lines. An applied current imposes a Lorentz force on these lines, but motion of the lattice will always be inhibited by pinning to material defects. Beyond a certain 'critical' current densi...
