| Abstract: | Ti/Pr0.7Ca0.3MnO3/Pt and Ti/Pr0.7Ca0.3MnO3/La0.67Sr0.33MnO3/Pt heterostructures are prepared using a pulsed laser deposition (PLD) technique, and the resistive switching of the heterostructures is investigated. The Ti/Pr0.7Ca0.3MnO3/La0.67Sr0.33MnO3/Pt heterostructure, which has a La0.67Sr0.33MnO3 modulation layer, shows superior characteristics of resistive switching. In particular, the switching ratio and the fatigue properties are improved greatly in this heterostructure. The mechanism of resistive switching in Ti/Pr0.7Ca0.3MnO3/La0.67Sr0.33MnO3/Pt heterostructure is also discussed in this paper. |
