Abstract

Resistance switching effect caused by external electric field was investigated in Pr 0.7Ca 0.3MnO 3 (PCMO) thin films grown on (001)-oriented LaAlO 3, by using different metallic (Al, Pt, Au, Ti) electrodes. When Al was used as one or both of the electrodes, PCMO thin films exhibited resistance changes upon reversing voltage polarities. Nonlinear, hysteretic current-voltage loops were observed. Our measurements showed that the total resistance of the samples were dominated by interfacial resistance. Such kind of device structure can find applications in non-volatile memory devices.
