چکیده انگلیسی
In this work, the change of the local atomic structure in BaTi1âxZrxO3 ceramics was investigated by synchrotron X-ray absorption spectroscopy technique. The X-ray Absorption Near-Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS) spectra at the Ti K-edge were measured and compared with simulated spectra. The results show that an increase of Zr content in Ba(Ti,Zr)O3 lattice structure affected significantly the phase transition behavior and the local structure surrounding the Ti absorbing atom. More importantly, the information on the locally determined structures and its relation to the phase transition characteristic from relaxor ferroelectric to polar clusters in Ba(Ti,Zr)O3 system were obtained and discussed.
