Sažetak
A systematic study of the Raman spectra of Y-Ba-Cu-O superconducting
materials under different experimental conditions clarifies the controversial results given in the literature. Under the determined conditions and thanks to the micro-Raman technique, reproducible polarized Raman spectra can be obtained and a coherent assignment can be suggested for YBa2Cu307and EuBa2Cu307.For YBa2Cu3(OjF);, the introduction of fluorine atoms was found to be localized in pyramidal CuO units rather than in CuO chains.
