Description
A HREM study on the defects in the high-Tc superconductor Y-Ba-Cu-O discovered recently is reported. It is found that there are large amounts of local lattice distortions, point defects, and misarrangements of Y or Ba atoms within the specimens observed. HREM images of grain boundaries and interfaces between the crystalline state and so-called intermediate-ordered state are obtained. It is found that the tripled period lattices are distorted, especially near the interfaces. (author)
