Abstract

We report the magnetic field-induced superconductivity in Sr_{1- x}K_xBiO₃ 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 Sr_1-xK_xBiO₃ are discussed.
