Frequency and temperature dependent intrinsic electric properties of manganese doped cobalt ferrite nanoparticles

Structural characteristics, cation distribution, and elastic properties of Cr3+ substituted stoichiometric and non-stoichiometric cobalt ferrites

“…2,3 In particular, cobalt ferrite (COF) has got enormous importance both in technological as well as biomedical applications. [3][4][5][6][7][8][9][10][11][12][13] Intensive studies on COF have been carried out with varying doping and/or substituting the divalent or trivalent cations and synthesizing them by different methods. 3,14,15 In order to conrm the crystallinity and the phase of the synthesized materials, Rietveld renement has been signicantly used on the X-ray diffraction (XRD) data of the samples.…”

“…3,14,15 In order to conrm the crystallinity and the phase of the synthesized materials, Rietveld renement has been signicantly used on the X-ray diffraction (XRD) data of the samples. 1,[9][10][11]16 Amri et al 1 have calculated the theoretical lattice parameters along with hopping lengths, oxygen positional parameters, cationcation and cation-anion bond lengths of Ni-Zn-Al ferrite. Kumar et al 14 have reported on the estimation of the lattice parameters by using Nelson-Riley (N-R) function, intrinsic strain and crystallite size by using Williamson-Hall (W-H) method.…”

Influence of Mg substitution on structural, magnetic and electrical properties of Zn-Cu ferrites

“…On the other side, soft ferrites behave as good conductors at low magnetic field due to their low coercivity, whose magnetization can be easily altered. Soft ferrites have a lot of useable area in the electronic industries such as inductors, transformer cores and microwave components [4,10,11], owing to their low cost, high resistivity and permeability, temperature stability, and low loss [12,13]. For biomedical applications, both soft and hard ferrites are used due to high magnetic anisotropy and biocompatibility [14].…”

High permittivity, breakdown strength, and energy storage density of polythiophene-encapsulated BaTiO3 nanoparticles

“…Such a behavior of dielectric materials is widely accepted. In the low-frequency region that corresponds to the high resistivity of grain boundaries, more energy is required for electron hopping, thus, increasing the loss [27,28]. In the high frequency region that corresponds to the higher conductivity, energy required for the hopping of electrons is less and therefore, the loss decreases [27,28].…”
