Description

Intergrowths, stacking faults and dislocations have been investigated by transmission electron microscopy in (Hg, Re)Ba2Ca2Cu3O8+δ and HgBa2CaCu2O6+δ bulk superconductors. The stacking fault vectors and the Burgers vectors of partial edge dislocations associated with the nucleation or the annihilation of [Ca-CuO2] bilayers in the unit cells of both compounds are derived by different methods. We discuss the influence of uniaxial stresses on intergrowth propagation and also mechanisms yielding strain relaxation around intergrowths. (copyright 2005 WILEY-VCH Verlag GmbH and Co.
