Structural and dielectric behaviors for Mg0.5Co0.5Fe2O4 spinel ferrite synthesized by sol–gel route

Crystal structure and optical characterization of a new hybrid compound, C6H9N2FeCl4, with large dielectric constants for field-effect transistors

“…At low frequencies, the produced materials had greater ε ′ values, indicating that they might be good candidates for low-frequency energy storage. 57 Similarly, the ε ′ values fall as the frequency rises, improving the energy storage capacity. 58 Furthermore, the dielectric constant values rise as the temperature increases at a certain frequency.…”

Investigation of structural, morphological, and transport properties of a multifunctional Li-ferrite compound

“…The failure of the Summerfield scaling approach is due to the dissimilar dynamics of the load carriers over the studied frequency and temperature ranges. 67 Such behaviors are possibly related to an alteration in the load carrier density or change in the accessible pathways for the conduction transport number with temperature. 67 The presence of various available pathways ensures the conduction transport.…”

“…67 The presence of various available pathways ensures the conduction transport. 67 The Summereld scaling deviations are corrected using the Random Barrier Model (RBM). Then, the master curves should be restructured and introduced by modifying the scaling frequency axis y s by s dc T T T 0 a , as depicted in Fig.…”

Unusual semiconductor–metal–semiconductor transitions in magnetite Fe3O4 nanoparticles

“…The fundamental requirements for such applications are the creation of soft ferrimagnetic characteristics at room temperature, high electrical conductivity, reduced eddy current loss, and chemical stability. 6 Several studies have been published on the magnetic and electrical properties of different Fe 3 O 4 derived compounds such as CoFe 2 O 4 , 7 MnFe 2 O 4 , 8 Co 1.25 Fe 1.75 O 4 , 9 Ni 1− x Zn x Fe 2 O 4 , 10 Mg 0.5 Co 0.5 Fe 2 O 4 , 11 and Ni 0.4 Cu 0.2 Zn 0.4 Fe 2− x Dy x O 4 spinel ferrite nanoparticles. 12 From these studies, we found that the magnetic exchange interactions and charge carriers hopping mechanism in these ferrites are considerably influenced by the cation distribution, surface spin structure, interparticle interactions, magnetocrystalline anisotropy and surface morphology.…”
