摘要：

The structural-micro structural characterization and defect structure of Ru based magnetosuperconductor RuSr2Eu1.6Ce0.4Cu2O10-delta has been investigated by selected area electron diffraction pattern and high resolution electron microscopy. Under the present investigations, RuSr2Eu1.6Ce0.4Cu2O10-delta magnetosuperconductor shows the presence of both Ru-1222 and Ru-1212 phases. Analysis of the selected area electron diffraction pattern indicates root 2a x root 2a x c superstructure in Ru-1212 while Ru-1222 phase does not show the presence of superlattice structure. A careful and detailed investigations of the HRTEM image shows the presence of defects like 90 degrees domains, intergrowths, and dislocations. (C) 2008 Elsevier B.V. All rights reserved.
