| 内容記述 | To clarify the mechanism of the ferroelectricity in lead zirconate titanate, the local structure around Ti in a Pb(Zr0.7Ti0.3)O3 single crystal was investigated using X-ray fluorescence holography. The raw hologram data were contaminated by periodic noise due to the fluctuation of the incident X-ray intensity. The periodical noise were successfully removed using an inverse Fourier transformation method. From the filtered holograms, the atomic images around Ti could be reconstructed clearly. The reconstructions of B-site cations demonstrate an outward displacement of the neighboring Ti from the ideal B-site position, indicating an expansion of the local lattice around Ti. In addition, we found the splitting of Pb images and deduced the relative displacement between Ti and Pb atoms. These results contribute to the understanding of the local structure of PZT and could reveal the microscopic origins of very high dielectric and piezo-electric responses, both of which are essential for designing of new and improved materials. | |||||
