Granular structure appearance of the high temperature superconducting materials and exponential behaviour of their resistance near the zero resistance region were investigated. Power law fitting for. resistance versus temperature plot was obtained as R=1.6 x 10(-19)T(7.91). Twin boundaries, due to accommodation to the structural symmetry as the a and b axis are differentiated by oxygen uptake are a soul-cc of. a further weak-link picture. The scale range for. a twin boundary is commonly measured to be close to 1000 Angstrom.eninfo:eu-repo/semantics/closedAccessArticle3812Q4Q3815820WOS:000166933000005
