Change in Microstructure of Bi2Sr1.8Ca1.2Cu2Oy by Yttrium, Lanthanum Substitution and Ar Annealing

Advances in Superconductivity V

Abstract

Raman scattering has provided us with valuable information on microstructure of an oxygen around Cu for Bi2212 phase. Microstructure of the Bi2212 phase changes by Y or La substitution. The change in microstructure by Ar annealing is much smaller than that by Y or La substitution. The result supports our claim that mechanism of a rise in Tc by Ar annealing is different from that by Y or La substitution for the Bi 2212 phase. The change in micro-structure by La substitution is smaller than that by Y substitution.
