Abstract
We report the magnetic field-induced superconductivity in Sr1- xKxBiO3 superconductors. A reentrant superconducting- normal resistive transition is observed in certain samples and, by applying the external magnetic field (H) or increasing the current (I), the reentrant normal state goes back to the zero resistivity: the recovery of superconductivity by applying H or increasing I. The magnetotransport of investigation on different samples reveals an interesting relation between the observed field-induced superconductivity and the normal state transport properties. Possible origins of this unusual phenomenon in Sr1-xKxBiO3 are discussed.
