Abstract :
The local structure of PLZT has been examined by the means of neutron-powder-diffraction derived pair-distribution function (PDF). We find that atoms are displaced from the average periodic structure by a significant amount. The directions and magnitudes of the atomic displacements in PLZT are very similar to those found in PMN. The short and intermediate-range structural changes between ferroelectric, relaxor and antiferroelectric PLZT phases were compared
