摘要：

Superconducting properties in Ba2 DyCu3 O7 prepared by the method power calcination were studied. The compounds show a sharp superconducting transition at 94K, with narrow transition with (DELTA-T < 5K). They were investigated by d-C electrical measurements, AC susceptibility and X-ray diffraction. The pressure shift of T(c) for the compound is also reported.
