铁电和铁弹材料中的畴壁和畴前体对于铁电器件的优化和畴反转的新范例具有重要意义。任何基于畴壁或铁性前体的器件都需要关于结构相变以及介观结构的形成和演化的知识。在这篇综述中，共振压电光谱（RPS）被证明是一个方便的研究工具，用于铁性材料的表征。RPS同时测量与畴壁和铁性前体相关的弹性和压电性质，并将相变的发生和介观结构的形成与压电性质相关联。给出了铁弹性、铁电和弛豫材料的例子，包括SrTiO 3、BaTiO 3和PbMg 1/3 Nb 2/3 O 3。与初期的铁电KTaO 3的数据比较提供了深入了解的物理意义的相干温度和伯恩斯温度的铁电体，弛豫，并可能其他铁电系统。
Domain walls and precursors in ferroelectric and ferroelastic materials are of great importance for the optimization of ferroic devices and novel paradigms for domain switching. Any domain wall- or ferroic-precursor-based device requires knowledge about structural phase transitions and the formation and evolution of mesoscopic structures. In this review, Resonant Piezoelectric Spectroscopy (RPS) is shown to be a convenient investigative tool for the characterization of ferroic materials. RPS simultaneously measures elastic and piezoelectric properties related to domain walls and ferroic precursors and correlates the onset of phase transitions and the formation of mesoscopic structures with piezoelectric properties. Examples are given for ferroelastic, ferroelectric, and relaxor materials, including SrTiO3, BaTiO3, and PbMg1/3Nb2/3O3. Comparison of the data with incipient ferroelectric KTaO3provides insights into the physical meaning of the coherence temperature and the Burns temperature in ferroelectrics, relaxors, and potentially other ferroic systems.
