摘要：

Structural, magnetic and superconducting properties are studied in the Bi2Sr2Ca1-xYxCu2O8+delta system. The samples have shown a single phase Bi2Sr2CaCu2O8+delta structure. The highest T(c) 93.5 K is observed in the x=0.1 composition, with a decrease in T(c) for x up to 0.3 concentration. Superconductivity disappears in the samples with x>0.5. A sharp peak at 13 K is observed in the d.c. susceptibility measurements of the x=1.0 sample, which is attributed to a Y2Cu2O5 impurity.
