The structure and microstructure of the films have been examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results indicate that the crystal structure of the films is strongly sensitive to the oxygen deposition pressure; exhibiting sharp a-axis diffraction peaks, showing a texturation along (1 0 0) plane. A detailed description of the growth mechanisms and the substrate–film interaction is given, and the characteristics of the electronic transition and hysteresis of the phase transition are described in terms of the morphology, grain boundary structure and crystal orientation. The sharpness of the transition and the hysteresis upon heating and cooling are found to be strong functions of the crystal structure and microstructure (grain size).en© Science and Education Publishing.
