Maximum supercurrent in Josephson junctions with alternating critical current density
arXiv:0711.0294 · doi:10.1103/PhysRevB.76.174518
Abstract
We consider theoretically and numerically magnetic field dependencies of the maximum supercurrent across Josephson tunnel junctions with spatially alternating critical current density. We find that two flux-penetration fields and one-splinter-vortex equilibrium state exist in long junctions.
