Abstract / Description:We report the estimated intergrowth concentration of
Bi2Sr2CaCu2O8+delta (Bi-2212) layers embedded in Bi2Sr2Ca2Cu3O10+delta
(Bi-2223) single crystals grown using the
traveling-solvent-floating-zone technique. Possible phase
compatibilities in the liquidus region were discussed using the
chemical analysis data of the quenched molten zone of real-growth
experiments. The growth of Bi-2223 single crystals can be processed in
atmosphere with oxygen content of 5, 10 and 20% O-2. The content of
2.5% was found to be the lower oxygen limit. X-ray diffractometry was
used to reveal the intergrowth behavior. The values of both the 00L
peaks shift and width oscillate as a function of the Bragg index. These
oscillations are induced by random intergrowth of Bi-2212 layers in the
Bi-2223 matrix. The performed calculations, based on the experimentally
determined oscillation amplitude in the 1/d vs. L axes, have enabled us
to estimate the concentration of the Bi-2212 layers in the Bi-2223
matrix to be about 2%. (c) 2006 Elsevier B.V. All rights reserved.
