Structural and magnetic characterization of Co2+ substituted nano structured Copper-Zinc spinel ferrite

Synthesis and characterization of nanocrystalline spinel Zinc ferrite prepared by sol-gel auto-combustion technique

Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning electron microsco...

Structural and magnetic properties of Ti4+/Co2+ co-substituted cobalt ferrite

The variations in the structural magnetic properties of cobalt ferrite due to Ti4+/Co2+ co-substitution for 2Fe3+ are presented. The non-linear relation in the variation of the lattice parameter agrees with a previous study on cation distribution, which showed that the rate of substitution of cations into the A-sites and B-sites varies with Ti-concentration. Such variation in the rate of substi...

Magnetic Properties of Nano Crystalline Nickel, Samariumdoped Zinc Ferrite

Nano-particles of polycrystalline Zn Fe2 O4 are prepared using sol-gel method with Ni, and Sm. They are obtained as dried gel after the successful chemical reaction of their respective metal nitrate solutions in the midst of citric acid as catalyst. Synthesis of materials is confirmed using XRD from the report of single phase polycrystalline ferrite material. The magnetic properties of Zn-ferri...
