Dielectric hysteresis in single crystal BiFeO3

Solid State Communications, 1970
Single crystals of BiFeO3 of perovskite structure were grown with dimensions of greater than 1 mm from a Bi2O3 flux. Dielectric hysteresis loops were measured on these crystals. While the loops were not fully saturated, they confirm that BiFeO3 is ferroelectric.

Anomalous Thermal Hysteresis in Dielectric Permittivity of CaCu3Ti4O12

Applied Physics Letters, 2008
We herein report an anomalous thermal hysteresis in dielectric permittivity in CaCu3Ti4O12. The anomalous behavior was well explained in terms of the low-temperature Maxwell–Wagner relaxation induced by frozen carriers. A multirelaxation mechanism, i.e., the coupling of the dipole relaxation to the frozen carrier-induced and blocked carrier-induced ...

Dielectric Hysteresis and Rotation of Dipoles in Polyvinylidene Fluoride

Applied Physics Letters, 1980
Hysteresis curves of the linear dielectric constant, the electric displacement, and the IR absorbance at 1273 cm−1 were observed at −5 °C for a stretched film of polyvinylidene fluoride. The hysteretic polarization was obtained by subtracting the linear electric displacement from the observed electric displacement.

Observation of Bistability and Hysteresis in Optical Binding of Two Dielectric Spheres

Physical Review Letters, 2006
Using a dual-beam fiber optic trap, we have experimentally observed bistability and hysteresis in the equilibrium separations of a pair of optically bound dielectric spheres in one dimension. These observations are in agreement with our coupled system model in which the dielectric spheres modify the field propagation, and the field self-consistently ...

Hysteresis Mechanism in Low-Voltage and High Mobility Pentacene Thin-Film Transistors With Polyvinyl Alcohol Dielectric

Applied Physics Letters, 2012
In this letter, the hysteresis mechanism of organic thin-film transistors (OTFTs) with polyvinyl alcohol (PVA) as gate dielectric is studied. By examining OTFTs with a blocking polymer layer between gate and PVA or between channel and PVA, we confirm ...

Hysteresis in centrosymmetric CuPbI ₃ perovskite halide: apolar dielectric or orientable dielectric?

Journal of Physics: Condensed Matter, 2021
Abstract We demonstrated the change in polarization behaviour at the surface/interface before and after light through Havriliak–Negami equation of lesser known CuPbI 3 . We have synthesized CuPbI 3 through cold sintering technique and ...

Dielectric hysteresis in proteins

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973
Solid films of ovalbumin and of sodium polyglutamate both show dielectric constants of the order several hundred to several thousand together with marked dielectric hysteresis. It is suggested that these properties may result from ferroelectric behaviour and, if widespread among proteins, must have considerable physiological significance.
