Abstract
The HREM study of the fourth members of the tubular bismuth cuprates family, Bi4Sr8Cu5O19, Bi4Sr7LaCu5O19.5 and Bi4Sr8Cu3Fe2O20 is performed. The microstructure of most crystals is characterized by domains showing a regular atom stacking. A new monoclinic-5 tubular structure is identified twice in large domains.
