Precipitation Hardening in Ferroelectric Ceramics

Changhao Zhao et al.

Summary: The study presents a novel approach for electroceramics by utilizing precipitates to pin domain walls, improving piezoelectric properties and enhancing mechanical quality factor. This new method reduces hysteresis in electrostrain while slightly increasing the piezoelectric coefficient and electromechanical coupling factor.

Nanoscale bubble domains with polar topologies in bulk ferroelectrics

Jie Yin et al.

Summary: The authors demonstrate the achievement of self-confined bubble domains with multiple polar topologies, especially skyrmions, in bulk Bi0.5Na0.5TiO3 ferroelectrics. The phenomenon is driven by the interplay of bulk, elastic, and electrostatic energies of coexisting modulated phases. This leads to reversible and donut-like domain morphology evolution in the material.

Direct observation of domain wall motion and lattice strain dynamics in ferroelectrics under high-power resonance

Mihail Slabki et al.

Summary: The study measured domain wall motion and lattice strain dynamics of ferroelectrics at resonance using high-power burst excitation and in situ high-energy X-ray diffraction. The research established a general relationship between microstructural strain contributions and macroscopic electromechanical behavior, allowing for the prediction of high-power stability of ferroelectric materials. The results suggest that materials' stability during high-power drive is predominantly related to the basic chemical composition, while piezoelectric hardening mechanisms mainly influence small-signal behavior.
