Abstract
Transmission-electron microscopy of the high-superconductivity-transition-temperature oxide Y1Ba2Cu3Ox reveals the presence of planar defects along [110] direction more-or-less uniformly spaced (spacing ∼300 Å) and dispersed throughout the specimens. These defects persisted on cooling down to the transition temperature (93 K), but disappeared on heating above 400°C in in situ experiments inside the electron microscope. The possible role of these "domains" or interfaces in superconductivity is discussed.
