Electrical impedance and electric modulus approach of double perovskite Pr2ZnZrO6 ceramics

Journal of Materials Science: Materials in Electronics, 2013
The polycrystalline praseodymium zinc zirconate Pr2ZnZrO6 (PZZO) is synthesized at 1,150 °C by means of solid state reaction technique. X-ray structural analysis confirmed the formation of a single phase monoclinic structure at room temperature. The nonzero intercept in the Nyquist plot indicates the presence of an arc for frequency higher than the ...

Shear modulus of polyelectrolyte gels under electric field

Journal of Physics: Condensed Matter, 2001
The shear modulus of two polyelectrolyte gels poly(acrylic acid), a weak acid with small side groups, and poly(2-acrylamide-2- methylpropane sulfonic acid), a strong acid with large side groups, have been measured with and without application of an electric field across a gel sample swollen with water to equilibrium.

Complex Dielectric, Impedance, and Electric Modulus of CuMn2O4

Journal of Electronic Materials, 2019
Tetragonal distorted CuMn2O4 spinel has been prepared by a single-step method and its complex dielectric, impedance, and electric modulus measured with respect to frequency at different selected temperatures. In all the measurements, a frequency-dependent inflection point was observed above 170 K, revealing the cross-over in the grain and grain ...

Electric modulus powerful tool for analyzing dielectric behavior

IEEE Transactions on Dielectrics and Electrical Insulation, 2014
Complex electric modulus, defined as the inverse of complex relative permittivity, can be a significantly powerful tool for analyzing dielectric behavior of a polymeric insulating material, especially at relatively high temperatures, where complex permittivity usually becomes very high due to electrode polarization and carrier transport. In this paper,

Electric modulus and polarization studies on piezoelectric polyimides

Journal of Applied Polymer Science, 2011
AbstractThe piezoelectric polymeric sensors and actuators are widely valued because of their low density, availability to obtain complex shapes, and easy processing among other characteristics. However, there are not many useful piezoelectric polymers.

Dielectric response and electric modulus of Y2CrCoO6 perovskite

AIP Conference Proceedings, 2016
Y2CrCoO6 perovskite prepared by solution combustion method and sintered at 1073 K has been characterized by dielectric spectroscopy and electric modulus formalism. Temperature and frequency dependent measurements of permitivitty reveal that observed relaxation might be related to the hopping conductivity, i.e. universal dielectric response.

Dielectric relaxation, electrical conductivity measurements, electric modulus and impedance analysis of WO3 nanostructures

Journal of Alloys and Compounds, 2021
Abstract The electrical conductivity and dielectric properties of WO3 nanostructures were measured by impedance spectroscopy using 50 Hz–5 MHz frequency in steps of 100 Hz and 303–383 K temperature. The dielectric behavior is analyzed using real and imaginary parts of dielectric constant (e′), dielectric loss (e″), loss factor (tan δ), electric ...

AN INVESTIGATION OF β-ALUMINA ELECTROLYTES BY ELECTRIC MODULUS SPECTROSCOPY

Electrochimica Acta, 1977
Abstract Various types of β-alumina (including single-crystal cylindrical boules, Monofrax flakes polycrystalline sinters) have been investigated by electric modulus spectroscopy. The complex electric modulus is identical with the inverse complex permittivity, ie M *  ( e * ) −1 , and also related to the complex impedance by the equation M * 

Disadvantages of electric modulus formalism in description of electrical relaxation in solids

Ferroelectrics, 1996
Abstract Some wide-spread misconceptions associated with the usage of electric modulus formalism are analyzed. The most striking disagreement with reality is the wide-spread opinion about an ideal, Debye-like behavior of electrical relaxation in low-alkali quartz glass.

Electric field dependence of young's modulus of (TMTSF)2PF6

Synthetic Metals, 1993
Abstract We report on measurements of the Young's modulus (Y) and internal friction (1/Q) in (TMTSF) 2 PF 6 at 5.5K as functions of electric field. No changes ( Δ Y/Y, Δ 1/Q −4 ) are observed at fields up to 100E T , the threshold for SDW depinning, in contrast to what is observed for many sliding charge-density-wave materials.
