Thin films of lead magnesium niobate-lead titanate (PMN-PT) have been synthesized by a new and simple chemical solution deposition route based on the chelate process. Acetoin (3-Hydroxy 2- butanone) was used as chelating agent and methanol as solvent. Homogenous and crack-free films with thickness up to 1 ìm were deposited on Pt/Ti/SiO2/Si substrates by spin-coating. The microstructure and surface morphology of the films were characterized by X-ray diffraction and atomic force microscopy (AFM) techniques. Highly (110) textured films with a predominant perovskite phase and average grain size of ~200 nm were obtained. The dielectric and ferroelectric properties are investigated.ìm were deposited on Pt/Ti/SiO2/Si substrates by spin-coating.
