Enhanced domain dynamics in alternating current poled rhombohedral Pb(Mg1/3Nb2/3)O3–PbTiO3 single crystals
The understanding of domain dynamics in ferroelectric materials is crucial for optimizing their performance in piezoelectric and electro-optic applications. Although previous studies have focused on static domain structures and macroscopic characteristics, the time-resolved approach of domains remains largely unexplored. In this study, we compare the dynamic responses of direct current (DC) and alternating current (AC) poled [001]-oriented rhombohedral Pb(Mg1/3Nb2/3)O3–PbTiO3 (PMN–PT) single crystals using X-ray photon correlation spectroscopy (XPCS) during the application of external electric fields. Our results demonstrate that the AC-poled sample exhibit enhanced reconfiguration of domain variants in response to driving fields compared to the DC-poled counterpart, as evidenced by accelerated correlation decay and faster relaxation time. This phenomenon is attributed to enhanced reversible domain wall motion achieved through AC poling, which facilitates field-induced domain realignment. These findings provide insight into the relationship between dynamics and macroscopic properties in relaxor-PT single crystals for high-performance applications.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
