In this work we prepare nanocrystalline mixed ferrites by equilibrated low entropy routes with generic formula of MnxNi1-xFe2O4. Two series of samples have been prepared where “x” varies as 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 the samples have been prepared by chemical co-precipitation route. For the first calculated amount of salts of Mn, Fe and Ni were dissolved in deionized water and stirred for ...

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomateri...

Developing a method for preparing Ni and Mn ferrites was the main objective of this study due to importance these materials in high-frequency applications. These were made by assisting combustion with dried leaves Corchorus olitorius then heating them 700 °C. Several methods, including FTIR, XRD, TEM, SEM/EDX, used characterize ferrites. The thermal behavior, surface magnetic properties as-prep...

The hard ferrites called hexaferrites or hexagonal show excellent characteristics which makes them suitable for many potential applications. magnetic of these must be tweaked to meet the needs a certain application. This can fulfilled by making few modifications within crystal structure such as reduction size at nanoscale, changes in morphology, substitution divalent well trivalent metal cation...

A major issue in the industrial sector is highly efficient and economical treatment of hazardous dye-based colour effluents. Spinel ferrite nanoparticles are more prominent for their unique qualities, such as optical, catalytic, electrical, magnetic properties. Moreover, physical characteristics ferrites may be influenced well catalytic properties by substituting metals like magnesium. In this ...

The Nickel substituted Cu-Co-Zn-Ce nano ferrites, Zn0.15Co0.45Cu0.40-xNix Fe1.85Ce0.15O4 with x=0, 0.1, 0.20, 0.30, 0.40, were synthesized using the coprecipitation technique. sample sintered at 900 ℃ for 5h. structural, electrical, dielectric and magnetic properties of all prepared samples characterized by XRD, SMU2401, UV-Vis FTIR. powder X-ray diffraction patterns confirmed formation single-...

Nanomagnetic structures of hydrothermal NiZn ferrites sintered at various temperatures was studied in this work through Magnetic Force Microscopy (MFM) using different magnetically characterized tips. The magnetic patterns varied according to the tip employed and were correlated to the magnetic induced field generated by these different coated tips. NiZn ferrites were produced at 200°C by hydro...
