Although there has been extensive investigation into lead-free piezoelectric materials due to environmental concerns and E.U. legislation, lead-free alternatives do not yet offer competitive properties. Currently the mechanism by which lead based materials show improved properties is not well understood. Examining the short range order of PZT in un-poled and poled forms will provide an explanation and hence clues as to how to engineer lead-free alternatives. Pair distribution function (PDF) analysis provides the short and medium range coherence lengths necessary for understanding local structure.Aims - collect PDF data for poled and unpoled PZT samples across the compositional phase boundary. - Use the oxygen tilt peak to mark ferroelectric order
