四方铁电材料被极化以诱导压电效应所必需的各向异性。这种材料的极化本质上是一个定向过程。一种锆钛酸铅海军VI材料的极化和交叉极化极形织构测量显示了畴运动。由此产生的轴对称和三维织构证明了90°域运动对压电性的贡献。与初始极化步骤相比，交叉极化产生了较强的定向和较低的施加磁场。
Tetragonal ferroelectric materials are polarized to induce the anisotropy necessary for the piezoelectric effect. This poling of the material is inherently an orientation process. Pole figure texture measurements of poling and cross-poling in a lead zirconate titanate Navy VI material show domain motion. The resulting axisymmetric and three-dimensional textures demonstrate the contribution of 90° domain motion to piezoelectricity. Cross-poling results in strong orientations with lower applied fields than in the initial poling steps.
