About this Research Topic
Ferrites are regarded as better magnetic materials than pure metals because of their high resistivity, lower cost, easier manufacture and superior magnetization properties. Ferrites are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet. The different ferrites are magnetically classified as "soft", "semi-hard" or "hard" based on their resistance to being demagnetized (magnetic coercivity). The ferrites are structurally classified into four categories: spinel ferrite, hexaferrite, garnet ferrite and perovskite-type ferrite. With the rapid development and advancement of mobile communication and information technology, the electronic components with small size, high efficiency, and low cost are urgently needed. When the ferrites present a large surface/volume ratio (i.e when they are in the form of thin films or fine powders) they can be exhibited the various physical properties.
The physical properties of the ferrites are strongly dependent on the synthesis method, thermal/time treatment and different sintering atmosphere and temperature, and substitution of foreign ions. The main goal of this Research Topic is to bring together researchers in the field of the ferrite nanomaterials to present the modifications which have significant effects on the resulting properties and applications. This Research Topic aims to highlight the latest developments in the synthesis and further advance research into optimization and advancement of synthesis methods of the ferrites in order to design, characterize and achieve improved properties in view of the specific requirements of the wide existing and new application fields of these materials.
