摘要	The conduction relaxations of polycrystalline La(0.5)Ca(0.5)Mn(0.95)Fe(0.05)O(3) upon imposing rectangle electric current pulses (with minute time scale) are studied in details. We observe clear "overshooting" features of the conduction relaxation at both the front and rear edges of the current pulse so long as the pulse is sufficiently high. The Joule heating effect and the intrinsic stabilization of the ferromagnetic metal phase by the current pulse are linked in understanding our observations, and these effects may be applicable for resistance switching function.
