Bipolar resistance switching was investigated on La0.7Ca0.3MnO3 (LCMO) thin film with Al-Ag alloy top electrode (TE) including different Ag contents. The switching capability of Al-Ag/LCMO/Pt was greatly improved in Al-33%Ag TE structure compared to in Al-50%Ag TE structure. Switching times of faster than 100 ns and rewrite cycles of more than 400 were obtained while maintaining a ratio of resistance change larger than 1000%. The mechanism of resistance switching was explained by a model with interfacial nanostructured domains composed of Ag and insulator AlOx matrix, as previously proposed for Al-50%Ag/LCMO/Pt structure.
