Abstract

A simple phenomenological model of a weakly bonded superconductor is suggested. The model considers the transition from a single weak dangling bond to a disruptive two-dimensional structure in taking the IV characteristics. A way of finding weak bond distribution functions from the second voltage harmonic is suggested and justified. A functional dependence that corresponds to the weak bond current distribution density is determined. The maximum critical current of weak bonds in a superconductor is found. A function describing the IV characteristic, as well as the first and second voltage harmonics, is determined.
