A study on the structural–microstructural characterisation and defect structure of Ru based magnetosuperconductor, RuSr2Eu1.6Ce0.4Cu2O10−δ

The structural–microstructural characterization and defect structure of Ru based magnetosuperconductor RuSr2Eu1.6Ce0.4Cu2O10−δ has been investigated by selected area electron diffraction pattern and high resolution electron microscopy. Under the present investigations, RuSr2Eu1.6Ce0.4Cu2O10−δ magnetosuperconductor shows the presence of both Ru-1222 and Ru-1212 phases. Analysis of the selected area electron diffraction pattern indicates 2a×2a×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° domains, intergrowths, and dislocations.
