Determination of the current density distribution in Josephson junctions

Determination of the current density distribution in Josephson junctions

A technique is described for recovering the missing phase information for a set of critical current measurements as a function of an applied magnetic field I c( B). In many cases the current density j( x) across the boundary for a Josephson junction can be determined.
