Abstract

A theoretical model is suggested that describes the effect of misfit stresses on the structure and the transport properties of tilt boundaries in high-transition-temperature superconducting films. It is theoretically revealed here that misfit stresses are capable of inducing structural transformations of tilt boundaries, which give rise to local changes of grain-boundary misorientation and corresponding changes of the critical current density across grain boundaries.
