Abstract :
Recently, it has been revealed that properties of ferroelectric nanostructures depend on their size. The depolarization field has been considered as one of the major factors, which cause “size effect”. In this study, we investigated the influence of the depolarization field on the domain structure in tetragonal Pb(Zr,Ti)O3(PZT) nanorods. We fabricated PZT nanorods with 100 nm-4μm widths by focused ion beam, and evaluated their structures by synchrotron X-ray diffraction. There was clear difference in the domain fraction between film and nanorods.
