Cross-poling textures in a lead zirconate titanate piezoelectric material

Tetragonal ferroelectric materials are polarized to induce the anisotropy n ecessary for the piezoelectric effect, This poling of the material is inher ently an orientation process. Pole figure texture measurements of poling an d cross-poling in a lead zirconate titanate Navy VI material show domain mo tion, The resulting axisymmetric and three-dimensional textures demonstrate the contribution of 90 degrees domain motion to piezoelectricity. Cross-po ling results in strong orientations with lower applied fields than in the i nitial poling steps.
