Outline of Final Research Achievements

Temperature-dependent super structures in spinel-ferrite & Bi-layered perovskite ferroelectric films were found and its origin was clarified, while its strain field at their interfaces was calculated to show that the strain filed could cover all the ferroelectric matrix regions enough to modify its ferroelectric properties. The nanocomposite films with a different polar-axis orientation were successfully obtained to show a higher polarization along the out-of-plane direction detectable by PFM. For an efficient PLD synthesis of multi-component oxide films, a galvanomirror-scanning type PLD system has been newly developed, demonstrating a quick fabrication of BaTiO3-Ba0.7Sr0.3TiO3 vertical composition gradient films. Preliminary investigating their coercive fields for polarization reversal by PFM, an internal electric field in such vertical composition gradient ferroelectric films, which was theoretically predicted in the previous literatures, was suggested.
