Properties of nanoferrites are very sensitive to the method of preparation and sintering condition. Therefore, the selection of an appropriate process is the key to obtain high quality ferrites. Nanosize zinc ferrite has been the particular subject of study because of its unusual structural, ...
Magnetic Phase Diagram of Nanostructured Zinc Ferrite as a Function of Inversion Degree δ Magneticproperties of spinel zinc ferrites are strongly linkedto the synthesis method and the processing route since they controlthe microstructure of the resulting material. In this work, ZnFe2O4 nanoparticles ...
of ferrite devices. Properties of ferrites are found to be dependent on their chemical composition and microstructure, which in turn are governed by the preparation process. In our work we prepared five different compositions of nickel-zinc ferrites by using low temperature sol-gel technique ...
Following this technique avoids many of the outstanding problems that normally exist in conventional emulsion synthesis. Due to the simplicity of this process, it could also become a valuable starting point for the generation of other mixed and complex ferrites....

The elemental mapping shows the presence of Zn in the precursor, which further demonstrates the Zn doping, in good agreement with the XPS result. It should be noted that the adding of slight amount of zinc plays a critical role in controlling the leaf-like nanoplate morphology, which has ...

The most appropriate doping compounds are the spinel ferrites, and particularly the zinc ferrites, because of their good magnetic properties, band gap ranging between 1.0 and 2.0 eV (depending on chemical composition and synthesis method), chemical and physical stability in photodegradation medium, low...
Manganese zinc ferrites are technically and scientifically a very important class of ferrite materials because they possess a very high magnetic permeability and low core losses. These materials have been broadly used in electronic applications such as transformers, choke coils, noise filters, and ...
