Abstract
Thin films of charge-ordered manganates, Pr1−xCaxMnO3 (x=0.3,0.4) are shown to undergo electric current-induced insulator-metal (I-M) transitions, the transition temperature increasing with the current. The occurrence of I-M transitions in these films without prior laser irradiation is noteworthy. The films show interesting memory effects and some non-linearity in the I-V characteristics. The magnetic-field induced I-M transition in the films is independent of the current employed. At low magnetic fields, or at low currents, resistance oscillations occur due to temporal fluctuations between resistive states.
