Abstract

The effects of Ba additions on the compositional, microstructural, and magnetization properties of Bi₂Sr₂CaCu₂O_8+δ (Bi-2212) superconductors have been investigated. BaO₂ reacts with the Bi-2212 matrix to form second phase precipitates. SEM micrographs, pole figure analyses, and improved transport properties in self-field and high fields up to 17 T suggest significant influence on the development of texture in Bi-2212 due an addition of BaO₂. Magnetization measurements revealed that the pinning properties of optimally BaO₂-added Bi-2212 were not affected. To estimate the potential of BaO₂ additions to assist the formation of potential pinning sites, TEM investigations were carried out. The achieved results are presented and discussed.
