The lattice constants, density, porosity, dielectric constant and dielectric loss tangent were studied on a series of rare earth substituted strontium hexaferrites. The dielectric constant and dielectric loss tangent were measured in the frequency range of 20 Hz to 1 MHz at room temperature. The ...
A perturbation theoretical equation for the dielectric constant of polarizable dipolar fluids is proposed. For the fluctuation of the dipole moment, namely for the Kirkwood g-factor, a formula is given on the basis of Wertheim''s renormalized perturbation theory. Using this formula, a series expan...
CONDUCTANCE OF THE ALKALI HALIDES. II. CESIUM IODIDE IN DIOXANE—WATER MIXTURES1,2 The conductance of cesium iodide at 25° was measured in dioxane-water mixtures covering the range of dielectric constant 12.81 ≤ D ≤ 78.54. The data con......
This method is suitable for measuring dielectric properties of most materials, including biological materials, geological materials, fabrics, ceramics, and foods. Increase in temperature in the temperature range considered increases the dielectric constant and loss factor of this material. Further increases...
In order to improve the defects in single doping where the dielectric constant and dielectric loss increase or decrease at the same time, a new method of doping modification, co-doping, can be used. Co-doping will improve the dielectric constant and temperature stability of the material, which...

High dielectric constant ( κ) materials have become a necessity for down scaling of metal-oxide-semiconductor (MOS) based devices. Rare-earth oxides have been studied as alternative dielectric material to replace SiO 2 gate for future Si-based technology due to their excellent dielectric properties...
An increase in the dielectric constant (800 ± 15; 100 ≤ f ≤ 104 Hz) of PVDF without a coresponding increase in the dielectric loss is reported. This is realized by preparing sandwich structures composed of CNF/PVDF composite layers and a pure PVDF interlayer. The influence...
