A. Sattar et al., MICRO-RAMAN STUDY OF POLYCRYSTALLINE HAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-1.0)(DELTA (0.0), Journal of Raman spectroscopy, 28(12), 1997, pp. 1005-1007
Micro-Raman spectra of erbium-doped Bi-2212 are reported, The assignme
nt of the observed bands is made on the basis of the results of lattic
e dynamical calculations and known vibrational spectra of pure Bi-2212
and Y-123 systems. The characteristics of the observed bands seem to
depend mainly on the extra oxygen entering the samples due to Er dopin
