Abstract

The structure of the high-temperature superconductor GdBa2Cu3Ox (x ≈ 7) was examined by high-resolution transmission electron microscopy. The Gd-substituted superconductors, in contrast to the yttrium-based materials, contained a large number of planar defects corresponding to a shear vector of 1 6 [301]. Detailed image simulation enabled the defects to be identified as copper-rich regions.
