We propose to introduce a new branch of grain boundary engineering, namely grain boundary junction engineering.
The results are explained in terms of competition between grain boundary diffusion and grain boundary migration.
The driving force for grain boundary diffusion is the normal stress acting on the grain boundary.
Concerning the main intrinsic factor, Jc across the grain boundary decreases with grain boundary misorientation angle similar to that observed in the cuprates YBCO13,21.
