Abstract

Optical microscopy has proven to be a useful technique for obtaining general, qualitative information from the entire surface of YBa/sub 2/Cu/sub 3/O/sub 7-x/ samples. Micro-Raman spectroscopy is well suited for routine microstructural analysis of YBCO superconductors. We demonstrate the complementary use of both techniques for the analysis of polycrystalline YBCO. Observed colors of polarisation on YBCO were correlated with information provided by Raman spectroscopy on individual grains to deduce microstructural characteristics across the whole surface of a sample.
