Abstract
The texture and structure of polycrystalline films of Bi-Sr-Ca-Cu-O
prepared by the paint-on method on alumina substrate has been
investigated. A large variety of texture strength has been obtained as a
result of various processing of 2:2:1:2, 1:1:1:2, 1:1:2:2 and 2:2:2:3 compounds.
The X-ray diffraction analysis and measurements of conductivity have
shown the presence of a low Tc phase. Imaging of the magnetic field
distribution using the Faraday effect and the critical current measurements
demonstrated that the critical current is very low. SEM observation of the
microstructure indicate that the possible reason of low critical current
density is a weak link between high Tc grains.
