“…7 Moreover, the larger ionic radii Nd 3+ ions replace Fe ions at the octahedral site of the ferrites which results in improved magnetic and electrical properties of the ferrites for the high-frequency application. [8][9][10] X. Wu et al 11 synthesized Ni 0.5 Zn 0.5 Nd x Fe 2Àx O 4 (0.0 # x # 0.12) samples by calcining oxalates in air. They reported that magnetic properties were improved aer doping with neodymium.…”

“…[ 16 ] For x ≥ 0.2 the plane splitting observed due to secondary phase of α‐Al 2 O 3 may be due to insufficient reaction between Fe 3+ and Al 3+ . The true value of the lattice constant of ZC ferrites was calculated using Nelson–Riley extrapolation function F(θ) with the help of following relation, [ 17 ]

F (θ) = \frac{1}{2} (\frac{co {normals}^{2} θ}{\sin θ} + \frac{co {normals}^{2} θ}{θ})

Cobalt substituted zinc ferrite aluminate series with compositional formula Zn1‐xCoxFeAlO4 (x = 0.0, 0.2, 0.4, and 0.6) is prepared by chemical sol–gel synthesis. The prepared samples are characterized by X‐ray diffraction (XRD), transmission electron microscope (TEM) technique. A cubic spinel phase is revealed by XRD analysis and confirmed from selected area electron diffraction (SAED) pattern. The true values of lattice constant are obtained from Nelson–Riley extrapolation plot, and lattice strain values are obtained with the help of Williamson‐Hall equation. The TEM image confirms average crystallite size of 31 nm. The dielectric study discloses the decrease of dielectric constant and loss tangent with the increasing frequency of applied field.

The present work describes the synthesis of Mn 0.5 Zn 0.5 Cr x Fe 2−x O 4 (x = 0.1, 0.2, 0.3) ferrite nanoparticles by solution combustion method and their detailed structural, electrical, magnetic, and optical characterizations. X-ray pattern represents the creation of a single spinel structure. In addition to this, the distribution of cations is also approximated from X-ray study which is then authenticated by the magnetization technique also. The crystalline size (23-21 nm) and lattice parameter (8.39-8.30 Å) are found to shrink with the rise in chromium ions. A decrease in saturation magnetization (0.80-0.64 emu/g) and remanent magnetization (0.05-0.03 emu/g) is found with the rise in chromium ions, while the coercivity is found to increase (83-123 Oe) through the adding of chromium ions. FTIR predicted the two absorption bands (ν 1 and ν 2) near 600 and 400 cm −1. Dielectric constant and loss tangent were observed to decrease with an increase in frequency, whereas AC conductivity attains a nearly constant value at a lower frequency and observed to increase at higher frequencies with the addition of dopant.
