“…It is observed that as the temperature increased, the radius of the semicircular arc decreased. This behavior was also reported by Behera et al [57] for NiFe 2 O 4 ferrite, which was prepared using high-energy ball milling followed by a solid-state reaction technique.…”

In this study, the plasma arc discharge process was employed to synthesize nanocrystalline Cu0.5Ni0.5Fe2O4 ferrite powders. The formation of a spinel-type structure of ferrite has been confirmed using X-ray diffraction. X-ray diffraction analysis conclusively verified the formation of a spinel-type ferrite structure. The investigation involved studying the frequency and temperature dependence of dielectric permittivity, dielectric loss, and DC/AC conductivity over a broad frequency range (1 kHz–1 MHz) in a temperature range of 298 K–403 K. The highest value of the dielectric contestant (4746) is observed at a frequency of 1 kHz and temperature of 313 K. A maximum in the DC conductivity is observed at 403 K, which can be ascribed to the combined effects of thermally activated hopping and an increase in the concentration of both n-type and p-type charge carriers at higher temperatures.

Herein, we delineate the enhancement of the dielectric properties of an anionic dye doped triglycine acetate crystal for the first time. Single crystals of pure triglycine acetate (TGAc) and reactive orange 16 (RO16) dye-doped (0.01, 0.03 mol%) triglycine acetate were synthesized with an intention to enhance the strengths of pure TGAc crystal using slow evaporation process. The crystalline structure and phase purity of the grown crystals were analyzed using Powder XRD studies. The frequency dependence of real and imaginary part of dielectric constant, loss tangent, real and imaginary part of impedance, electrical modulus and ac electrical conductivity have been investigated. The dielectric constant and dielectric loss for the grown crystals, have been found to decrease with increasing frequency. The decrease in permittivity and dielectric loss with an increase in applied field frequency is as per Maxwell-Wagner theory. The Cole-Cole plot implies that the mechanism of conduction is mainly due to bulk resistance. The enhanced dielectric constant of the doped crystals confirms the appropriateness of the developed crystals for energy storage capacitor applications.
