Abstract

We report X-ray and chemical properties, phase transition, magnetic susceptibility and superconducting transition temperature of Ba_2(1-x)Sr_2xYCu₃O_7-y. Structural instability was detected for sample with x≥0.6. Phase transition occurs at oxygen number of 6.6. Anomalies in magnetization curves at 4.2 K were detected. The T _c decreases linearly from 92 to 80 K with an increase of x. Strontium and oxygen contents are parameters correlated with the depression of T _c.
