We have analysed in terms of static hyperfine field distributions the Mossbauer spectra of mixed Zn-Mg ferrites. Typical features of semi-spin glasses are observed both in average and locally: in each sample, the relevant data are smeared out in a way which reveals the behavior of the series.

Abstract This paper presents the results of laboratory research on influence heat treatment corrosion resistance austenitic steels (Cr-Ni, Cr, Mn, Cr-Mn-Ni), that may extend under certain conditions and ferrites semi-ferrites chrome steels.This type intercrystalline was observed in other alloy systems due to media containing chloride ions.The experimental consist comparing structural changes ra...

Abstract High-frequency soft magnetic ferrite ceramics are desired in miniaturized and efficient power electronics but remain extremely challenging to deploy on account of the loss ( P cv ) at megahertz frequencies. Here, we prepared NiCuZn with superior high-frequency properties by V 2 O 5 Bi 3 synergistic doping, which proves be a potent pathway reduce The sample doped 800 ppm yielded most op...

Computer-aided design (CAD) of ferrite microwave devices requires an accurate, yet simple mathematical model of the permeability of polycrystalline ferrites. Contrary to earlier mathematical models, the model described in the present paper takes account of the variation of dc moment with bias field, and incorporates the "low-field loss" observed in ferrites, when magnetized incompletely. Typica...

Lanthanum substitution on spinel Nano particles has a significant repercussion the several features of materials. Sol–gel (auto-ignition) allowed for rare earth lanthanum ion (La3+) ferrite with composition SrLaxFe2-xO4 (where 0.00 ≤ x 0.10). As result base’s presence, systems structural, magnetic, electrical, and magnetic properties are all modified. X-ray diffraction (XRD) assessed structural...
