| Abstract: | The PMN-PT relaxor ferroelectric thin films were prepared,using inorganic salt as raw material,citric acid and EDTA as complex chelating agent,ethandiol as solvent.Influence of properties for Pb-Mg-Nb-Ti complex metal-organic precursor on structure and quality of thin films was studied.The results show that for the formation of the required thin films the optimal concentration of the precursor is between 0.35 to 0..45mol/L,and addition of benzoic acid in the precursor is facilitated the formation of pervoskite phase(≥99%) in the films. |
