Abstract
We report the electroresistance (ER) effect tuned by oxygen stoichiometry in La0.5Ca0.5MnOz. ER value varies from positive to negative, and is enhanced with the absolute maximum approaching a percentage of several thousands with lowering of the oxygen content, and the underlying physical mechanism of ER effect varies with the oxygen stoichiometry. We give a reasonable explanation on the mechanism of ER effect for the self-doped La0.5Ca0.5MnOz. In addition, the observation of the ER effect tuned by oxygen content may open up new routes to potential applications.
