“…The cell volume (V) that is directly dependent on the lattice parameters increases with increase in the concentration of Zr 4 þ -Mn 2 þ contents. The bulk density (r m ), as deduced from the Archimedes principle [19], increases with increase in the dopant concentration level while X-ray density remains almost constant. The crystallite size (D) calculated by Scherrer formula [20] is found to be in the range of 35-52 nm.…”

“…З точки зору практичного застосування, такі важливі параметри, як коерцитивна сила та магнітна проникність, не є властивостями самого ферриту, а залежать, окрім хімічного складу, також від різних дефектів і полікристалічної структури, тобто від форми та розмірів зерен і пор [4][5][6].…”

The aim of this work was to create and study of ferrite nickel-cobalt powders, using sol-gel technology with participation of auto-combustion. Dependence of the initial permeability from the degree of substitution of cobalt cations on nickel cations is obtained. It is revealed that the crystallite size has a significant influence on the magnetic properties of the samples. With decreasing of crystallite size of nickel-cobalt ferrite Curie temperature decreases. It is shown that the smaller the particle size, the greater the thickness of the surface layer with significant violations of magnetic structure.

Nanoferrites of composition Mn 0.50 Mg 0.5−xNi x Fe 2 O 4 with 0.00 ≤ x ≤ 0.50 were prepared by the chemical coprecipitation method. The prepared nanoferrites were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), atomic force microscopy(AFM), dc electric resistivity and magnetic properties using vibrating sample magnetometer (VSM) to study the structural, morphological, electrical, and magnetic changes taking place with varying Ni and Mg concentration in the composition of the prepared nanoferrites. The XRD results indicated the formation of single spinel ferrite with crystalline size in the range of 16-24 nm. The lattice parameter (a) decreased with the decrease of the Mg concentration. IR reveals the presence of both high and low frequency bands due to tetrahedral and octahedral sites, respectively. Further information about the morphology of the nanoferrites was obtained from AFM and SEM measurements. Electrical properties indicate that synthesized samples have high resistivity. The magnetic hysteresis curves clearly indicate the soft nature of the prepared nanoferrites. Various magnetic parameters such as saturation magnetization (M s ), and remanence (M r ) are obtained from the hysteresis loops and observed to be dependent on the composition.
