Depairing critical currents and self-magnetic field effects in submicron YBa₂Cu₃O₇₋δ microbridges and bicrystal junctions
We report on depairing critical currents in submicron YBa₂Cu₃O₇₋δ microbridges. A small-angle
 bicrystal grain boundary junction is used as a tool to study the entrance of vortices induced by
 a transport current and their influence on the I–V curves. The interplay between the depai...

| description | We report on depairing critical currents in submicron YBa₂Cu₃O₇₋δ microbridges. A small-angle
bicrystal grain boundary junction is used as a tool to study the entrance of vortices induced by
a transport current and their influence on the I–V curves. The interplay between the depairing and
the vortex motion determines a crossover in the temperature dependence of the critical current.
The high entrance field of vortices in very narrow superconducting channels creates the possibility
of carrying a critical current close to the depairing limit determined by the S–S–S nature of the
small-angle grain boundary junction.
