Abstract

We report the metal-insulator transition in epitaxial Pr0.7Ca0.3MnO3 thin film by introducing oxygen vacancies, which assist the nucleation of ferromagnetic metallic domains in a antiferromagnetic insulating matrix. The hysteresis of the resistivity indicates the transition is first-order, and covers a broad temperature range from 80K to 220K. Such novel transport properties of the x=0.3 doped manganite may result from strong spin-lattice coupling which stabilizes the system to a metallic metastable state at low temperature.
