Abstract

We have studied the micro-structure of shock synthesized Tl2Ba2CuO6, shockprocessed YBa2Cu3O7 and 10% Ag-YBa2Cu3O7. The structural interpretation of the defects observed in these materials is discussed and compared with computer simulated images. Two planar defects with a stacking sequence of Cu-Ba-Tl-Ba-Cu and Cu-Ba-Tl-Tl-Ba-Cu-Tl-Cu-Ba-Tl-Tl-Ba-Cu in the Tl based oxide and a new defect sequence of Cu-Ba-Cu-Y-Y-Cu-Ba-Cu in the Y based oxides are reported here. An attempt is made to relate the change in superconducting properties observed to the defect structure present.
