Abstract

Abstract Results of resistivity, a.c. magnetic susceptibility, Hall effect and superconductivity for single phase Ba 2YCu 3O 7− δ are reported. The positive value of Hall constant above T c indicates that the carriers of the sample are hole-like in normal state and its concentration is about 1.1×10 21 cm -3 at room temperature. A large anomaly of R H near T c is observed which may be indicative of granular superconductivity or be related to the intrinsic quality of this class of oxides.
