“…Saturation magnetization value is obtained at room temperature is tabulated in Table 1 are relatively high especially at higher concentrations of copper content as compared with the results of Jadhav et al [10]. On the other hand, the obtained coercivities show lower values as compared with the same results.…”

“…In addition to their high nutrition quality egg-white proteins are well known for their gelling, foaming and emulsifying characteristics [8][9]. NiCuZn ferrites of composition Ni0.7−xCuxZn0.3Fe2O4 (x = 0, 0.2, 0.4, 0.6) prepared by citrate precursor method, characteristics are investigated and reported [10]. X-ray diffraction(XRD) confirmed the formation of single-phase cubic spinel structure.…”

“…Many methods such as sol-gel auto-combustion technique [16], chemical coprecipitation [17], citrate precursor method [18], oxalate precursor technique [19], and ceramic method [20] are used to prepare Ni-Cu-Zn spinel ferrite. Among them, the sol-gel auto-combustion method has unique advantages such as excellent composition control, low temperature process, low production cost, and better results.…”

Ni 0.8−x Cu 0.2 Zn x Fe 2 O 4 (x = 0.0 ≤ 0.6 with steps of 0.2) ferrite nanophase was achieved by sol-gel auto-combustion technique. The as-prepared samples were thermally characterized by thermogravimetry/differential thermal analysis to obtain firing temperature of the materials. The X-ray diffraction pattern indicates the formation of a single-phase cubic spinel structure and shows strong influence of the incorporation of Zn 2+ metal ions on the spinel structure. The annealing treatment does not alter the crystal structure but increases the crystallinity of the samples. The morphological investigations and nanometric sizes of the samples were studied by scanning electron microscopy and transmission electron microscopy. The crystallographic texture due to annealing and Zn 2+ ion doping was systematically investigated by Fourier transform infrared spectroscopy.

“…Gonchar and Andreev [4] have reported that Ni-Cu-Zn ferrites with less content of Zn could obtain high Curie temperature, but the initial permeability of Ni-Cu-Zn ferrites reached. The substitution of Cu brings about a structural phase transition accompanied by the reduction in the crystal symmetry due to co-operative John-Teller effect [5,6], which ultimately results in some interesting electrical and magnetic properties. Various investigations [7,8] studied the electrical and thermal power of the spinel ferrites and have found that they have semi-conducting properties of n or p-type.…”
