Chemical Solution Deposition Growth of La0.7Ca0.3MnO3 Films and their Electric Pulse Induced Resistance Change Effect
A simple chemical solution deposition method was developed for the preparation of La0.7Ca0.3MnO3 (LCMO) thin films. The LCMO thin films were prepared on Si/SiO2/TiO2/Pt substrates by spin-coating method, followed by heat-treatment at 900°C. The fabrication process of the LCMO thin film was investigated by means of TG-DSC, FTIR, XRD, FE-SEM and EPMA. The electric pulse induced reversible resistance switching is observed in the Ag-LCMO-Pt sandwich structure.
