Ag. Castellanosguzman et al., REFLECTED-LIGHT POLARIZING MICROSCOPY OF THE DOMAIN-STRUCTURE IN BI2SR2CACU2O8-DELTA, Revista Mexicana de Fisica, 40(5), 1994, pp. 761
Using polarizing light microscopy in reflected mode we have studied th
e domain structure in single crystals of the high-Tc superconductor Bi
2Sr2CaCu2O8-delta. This structure mainly consists of a high density of
{110} domain walls, however, we have observed, for the first time, th
e so-called ''puzzle domains'' in BSCCO, domains which previously had
been observed only in another high-Tc ceramic; Y1Ba2Cu3O7-delta.
