Abstract

Substitutional effects of strontium in La-Cu-O system and defects accommodating stoichiometric deviations have been investigated. The extended shear defects are analyzed using electron microscopy and their role in superconducting transport properties has been examined by magnetic measurements. The initial results suggest that the defects enhance flux pinning.
