摘要：

A method based on the measurement of the distribution of the magnetic field B(sz) produced by shielding currents in a superconducting Y-Ba-Cu-O disc has been used to detect macroscopic inhomogeneities of the sample. A small-active-area Hall probe was used for magnetic field measurement. The phase composition and microstructure of the sample were determined by the XRD method and SEM respectively. Regions with irregular distribution of B(sz), corresponding to degraded current-carrying properties, were found in the investigated sample. An attempt to correlate observed irregularities with some features of the phase composition and microstructure has been made.
