Abstract

The results of transport measurements on the oxide superconductor Y1Ba2Cu3O7−x in the presence of an external magnetic field with various dc currents are reported. The observed highly irreversible behavior and other peculiar features are analyzed considering the granularity and weak-link nature of the bulk oxide superconductors. This study confirms the nonideal type-II superconducting nature of the compound.
