Preparation of Pr0.7Ca0.3MnO3 nanocrystalline films by chemical solution deposition route

Mixed-valent manganites Pr1-xCaxMnO3 are the object of continuously growing interest in the field of superconductors and colossal magnetoresistance (CMR) materials. In this work, Pr1-xCaxMnO3 films were successfully prepared by a novel and simple chemical solution deposition method using Pt/Ti/SiO2/Si as the substrate. X-ray diffraction, FT-IR, SEM, AFM, electron microprobe analysis and Auger microprobe analysis were adopted for the characterization of the prepared material. It is proved that Pr1-xCaxMnO3 films obtained are of single-phase with perovskite structure. The constituent elements are homogeneous, and Pr0.7Ca0.3MnO3 particles are densely and compactly distributed in the films.
