We report the synthesis and characterization of ferrite nanocrystals which exhibit high crystallinity and narrow size distributions. The three types of samples including Zn ferrite, Mn ferrite, and Mn-Zn ferrite were prepared via a non-aqueous nanoemulsion method. The structural, chemical, and magnetic properties of the nanocrystals are analyzed by transmission electron microscopy, X-ray diffra...

The present work describes the preparation of chromium substituted magnetoplumbite ferrites from nitrate salts, and the effect of Cr on its structural and magnetic properties. Powders with nominal composition PbFeiz,Cr,O,, (1.0 < x S 6.0) were obtained by thermal decomposition at 920 "C of coprecipitated hydroxide-carbonate mixed salts. A complete substitution of Fe3* by cr3' was found and the ...

The aim of this study was to the structure, morphology, magnetic, and magnetorheological properties cobalt cobalt-zinc ferrite powders be used as a functional component fluids. Ferrites CoFe2O4 Co0.65Zn0.35Fe2O4 were obtained by combined hydrolysis inorganic metal salt in aqueous solutions followed thermal treatment precipitates. ferrites studied means X-ray phase analysis, scanning electron mi...

Cost-effective and controllable synthesis of M0.25Ni0.15Cu0.25Co0.35Fe2O4 (M2+ = Mg2+, Mn2+, Cd2+) ferrites via the sol–gel auto-combustion technique. The impact divalent cations on structural, dielectric, optoelectrical properties was examined by XRD, FTIR, Raman, LCR, UV–Vis, two probe I-V measurement techniques. crystallite size 52.66 nm, minimum specific surface area observed 5.1507 m2/g fo...
