Structural Defects in Thin Films Of High TC Superconductors


In this short report, we describe some of the structural defects present in laser deposited Y-Ba-Cu-O thin films. Many of the defects observed are polytypoidic variants, related to the layered structure of these cuprates. One possible model by which flux pinning can be achieved is presented.
