Evidence of double-loop hysteresis in disordered ferroelectric crystal

Double-loop electric-field vs polarization hysteresis is investigated in a depoled compositionally disordered lithium-enriched potassium tantalate niobate crystal. Comparing electro-optic response

Dielectric spectroscopy of ferroelectric polymers

Comprehensive review on Froehlich entropy estimation: a technique to investigate the state of order in condensed matter

The so-called Fröhlich entropy is the entropy variation of a material under the application of an electric field. This quantity can be calculated, under suitable hypotheses, directly from the



Prenematic behavior of the electric-field-induced increment of the basic thermodynamic quantities of isotropic mesogenic liquids of different polarity.

Temperature dependences of the static dielectric permittivity and its derivative, obtained for isotropic mesogenic liquids composed of the molecules of different polarity in relation to the basic

Simple derivation of the Maxwell stress tensor and electrostrictive effects in crystals

Local equilibrium and energy considerations in an elastic dielectric crystal lead to a simple derivation of the Maxwell stress tensor in anisotropic dielectric solids. The resulting equilibrium

What insight can be gained from the nonlinear responses that are not available from dielectric relaxation results obtained in the linear regime are emphasized.

Free energies in the presence of electric and magnetic fields

We discuss the different free energies and Hamiltonians for materials in static electric and magnetic fields and which choice is the most appropriate for statistical mechanics calculations. We also

XCVI. Theory of barium titanate

Summary The theory of the dielectric and crystallographic properties of barium titanate is considered. By expanding the free energy as a function of polarization and strain and making reasonable

Fluctuations and thermodynamic properties of anisotropic solids

We present a direct calculation of fluctuation formulae that relate strain and kinetic energy fluctuations to the adiabatic compliance tensor, the constant stress specific heat, and the constant

Electrorheological Source of Nonlinear Dielectric Effects in Molecular Glass-Forming Liquids.

It is found that the field-induced increase in viscosity constitutes a significant source of nonlinear dielectric behavior, which occurs for both dc and alternating current fields.

Derivation and implications of the symmetry property of the permittivity tensor

The simplest way to establish the symmetry of the permittivity tensor is found to be based on the first law of thermodynamics. Expressions of energy density and the interpretation of Poynting’s
