Abstract
Relaxor ferroelectric materials PZT-PZN and PZT-PNN were prepared by columbite method. The structural change was investigated by Synchrotron X-ray Absorption Spectroscopy (SXAS) at Zr L3-edge. The results show structural change of both systems affects to white line (WL) intensity significantly as revealed by simulated spectra. At the MPB composition 0.7PZT-0.3PZN shows the enhance magnitude change as structure change from tetragonal to only rhombohedral phase. While the MPB composition 0.8PZT-0.2PNN shows the slight change of magnitude of WL intensity which mixed phases of rhombohedral and tetragonal. Therefore, the MPB composition of PZT-PNN system clearly conclude that is 0.7PZT-0.3PZN but the MPB of PZT-PNN system could not be conclude like that because the structure slightly change.
