dc.description.abstract | We study the structural and transport properties of a heavily oxygen-reduced region that is formed by electrical injection of a large amount of oxygen vacancies into a Bi0.7Ca0.3FeO3-delta thin film. In electroforming, the epitaxial as-grown state is transformed into a disordered, polycrystalline phase. Nonohmic current-voltage relations, which can be interpreted as a space-charge-limited conduction, appear at low temperatures. As temperature increases, the curvature of the current-voltage relationship gradually changes to be nearly ohmic at and above 100 K. The maximum value of magnetoresistance, as large as -2.6% at 90 kOe, is attained at the same temperature of similar to 100 K, which is significantly larger than -0.1% at 25 K and -1.3% at 300 K. | - |
