摘要：

A high-T(c) yttrium cuprate superconductor was obtained via oxalate coprecipitation. J(c) versus B measurements on the sample showed anomalous behaviour: the curve for increasing b is less steep than is usual at fields above 0.5 mT, while a characteristic different from the typical single maximum shape is obtained for decreasing B. These features might be taken into account for improving the J(c) versus B response in Y-Ba-Cu-O superconductors.
