Ferrites are the important material for memory devices. In this we discuss ferrites in detail with their classification, preparation method to applications. We also present a brief introduction about hard and application materials that offer distinct electrical magnetic features helpful various It is noted spin transmission torques may change magnetization through current travelling tunnel inte...

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-...

When highly divided spinel fenites become reactive enough with oxygen, to allow the oxidation of the Fe ions at low temperature and of substitute cations too, when these cations are capable of different valence states. We prepared fine particles of spinel ferrites substituted by Mn, Mo, Cu, by "chimie douce", especially from oxalate precursors and used them to reveal and to study the oxido-redu...

Barium substituted nanocrystalline ferrites with chemical composition BaxCa1-xFe2O4 (x =0.0 to 0.25) BCAF were prepared by solution combustion method. The phase formation of mixed spinal structured ferrites was confirmed by PXRD analysis. The average crystallite size was calculated using Debye-Scherrer formula and it was found to be in the range of 27-44 nm. Surface morphology was analyzed by S...

The magnetic properties of nano-crystalline CoMxFe2 xO4 (where M=Gd and Pr and x 1⁄4 0; 0.1 and 0.2) powders prepared by a citrate precursor technique have been studied by using vibrating sample magnetometer (VSM). The crystallite sizes of the materials were varied by altering the synthetic conditions and are within the range of a minimum of 6.8 nm and a maximum of 87.5 nm. The materials were c...
