摘要: We report the observation of reversible electroresistance in a metallic film La0.67Sr0.33MnO3 (LSMO). The transport behavior Ag/LSMO system is found to be sensitive external electric field, and switching resistance between two definite resistive states can induced by pulses different polarity. current-voltage relation, measured tuning bias voltage, significantly nonlinear, asymmetric against field polarity, hysteretic increase/decrease processes. This relation well described simple equation I=σV+kVn with n being number 1.8 2.4. It that rough surface LSMO favors effects.
