✦ Synopsis

By measuring the magnetoresistance, susceptibility, critical current and superconductivity of a series of high-T c ceramic samples with different microstructur~ the correlation between magnetic state and microstructure of the samples have been studied. The results indicate that the samples' magnetic states are strongly dependent on their microstructure and the superconductive glassy state only exist in some microstructural states, which suggests that the superconductive glassy state of high-Tc oxides is a extrinsic property,
