Ferrites represent a class of materials that are extensively studied due to their electrical and magnetic properties. These materials are widely used both in electrical and in electronics industry for the fabrication of devices and components such as high-density magnetic core of read/write heads for high-speed tape or disk recording. It has been proved that some ferrites can be successfully utilized in low-temperature water splitting thermochemical cycles.Synthesis and application of magnetic nano-particles with diameters of a few nanometers is a subject of intense research because of their unique properties that make them attractive, both from the scientific value of understanding their properties, and the technological significance of enhancing the performance of The high-energy milling as a solid-state processing method has been the subject of great interest in recent years. The highly non equilibrium nature of the milling process creates the opportunity to prepare solids with improved and/or novel physical and chemical properties. the existing materials.
