Superdomain dynamics in ferroelectric-ferroelastic films: Switching, jamming, and relaxation

Effect of temperature and humidity on dielectric and impedance properties of K(Nb0.8Ta0.2)0.99Mn0.01O3 electroceramics

“…A large number of researchers from various scientific communities are searching for a novel ferroelectrics material with significantly large dielectric constant, low tangent loss, large polarization, large piezoelectric coefficients, and low coercive field due to their potential applications as memory elements, sensors, actuators, transducers, dielectric filters, oscillators, ultrasonic wave generators, positive and negative temperature coefficient devices, microwave appliances, etc [1][2][3][4]. The choice of the material for device fabrication is driven by their unique physical and chemical properties such as dielectric constant, tangent loss, resistance, capacitance, conductivity, and microstructural relation over a wide range of temperature and frequency.…”

Mesoscopic origin of ferroelectric-ferroelectric transition in BaTiO3: Orthorhombic-to-tetragonal domain evolution

“…Thus, although each effect involves merely one type of domains-orthorhombic or tetragonal, the pre-and post-transition mechanisms have to be discussed within the framework of the ferroic phase transformation. Figure 4 and Video SI1 demonstrate that these quasi-periodic wrinkles 26 exist in the orthorhombic phase, just before the wavefront arrives. As the wavefront progresses, wrinkles next to the wavefront (but yet at the native orthorhombic phase) dissipated, while new wrinkles appear further away.…”

Ferroelectric Relaxor Quantum Crystals

“…There are a total of four patterns predicted for domain instabilities (shown below from Hohenbrg and Krekhov, Figure 7,), and we have recently illustrated all four experimentally [31]. Note that the chevron pattern (next to top panel) can maintain domain width on both sides of the reflection plane or change width; this width change can be an integer ratio (doubling, tripling .…”
