Abstract

We report a new reentrant superconducting-normal resistive transition observed in the Sr_1-xK_xBiO₃ superconductor. Unlike the previous reports about the reentrant resistive transition where the superconducting region becomes reduced and finally resumes the normal state by increasing the external magnetic field (H) or the current (7), we observed the recovery of superconductivity induced by applying H or increasing I. Subsequent dc magnetization measurement shows a gradual decrease of the diamagnetic susceptibility - appearance of the paramagnetic, Meissner effect - at low fields (H < 50 Oe) in the same temperature range where the reentrant normal resistivity was measured. The sample dependence of the reentrant resistive transition suggests the important role of grain boundaries in our samples. Possible physical origins of the field induced superconductivity observed in Sr_1-xK_xBiO₃ are discussed.
