Textured (Tl-Bi-Pb)-1223 thick films
Sprache des Titels:
Englisch
Original Kurzfassung:
Screen printing was employed to fabricate thick films of the composition (Tl0.6 Bi0.16 Pb0.24 )(Ba0.1 Sr0.9 )2 Ca2 Cu3 Oy on polycrystalline Y2 O3 -doped
ZrO2 substrates. The influence of the screen printing procedure, the heat-treatment of the films and additional compaction on the texturing of the superconducting
crystallites and on the electrical properties of the superconducting films have been studied. X-ray diffraction ascertained the high phase purity of the material and
allowed calculation of the degree of texturing. Scanning electron microscopy in combination with EDX and optical microscopy in normal and polarized light yielded
information about the microstructure of the films. T c (0) values of 118 K and transport critical current densities in the range of 10 kA cm-2 at 77 K were obtained for
the best specimens.
