Abstract

Well-defined metal-insulator-metal trilayered structures composed of epitaxiAlPr_0.7Ca_0.3Mn_O3 insulator layers, epitaxial LaNi O3 bottom electrodes, and Al metal top electrodes were fabricated on LaAlO₃ (100) substrates. The I-V characteristics of the trilayer structures show electric-field-induced resistance switching. The resistance switching ratio of the heterostructures was up to 100 when positive and negative pulsed voltages were applied. Detailed I-V analysis indicates the importance of both trap-controlled space-charge-limited current and Poole-Frenkel effect in resistance switching at AlPr_0.7Ca_0.3Mn_O3 interfaces.
