Abstract
The Ba isotope effect in Ba2YCu3O7-δ ceramic superconductors was studied by the Meissner effect. 134Ba-rich Ba (the weight of 134Ba being about 2.8 atomic units lighter than that of naturally obtained Ba) was introduced to obtain an isotope shift in T c. No clear shifts in T c are observed over the experimental resolution limit of temperature measurement.Keywords
