We report the observation of a reentrant superconducting-normal resistive transition in Sr1-xKxBiO3 super-conductors. In contrast to previously reported reentrant resistive transition behaviors, the reentrant resistivity appearing at zero magnetic field is suppressed to zero by applying an external magnetic field (H) or increasing the electrical transport current (I): an observation of the recovery of a zero resistive superconducting state induced by H or I. An analysis of the normal-state resistivity data indicates the important role that disordered junction barriers between superconducting grains might play on the observed reentrant resistivity behavior. Possible physical origins of this anomalous phenomenon are discussed.
