Ferrite Nanoparticles for Telecommunication Application

Ferrite nanoparticles have invited enormous scientific attraction because of their unique properties and up-and-coming applications. The ferrites are used in filter circuits and core materials for transformers. In turn is designed for broadband spectrum and antenna material in the telecommunication industry, like radio, television, mobile communication, etc. Eddy current losses are minimal at high frequencies because of ferrites’ significantly high resistance; therefore, a variety of applications can be exploited at extremely high frequencies, unlike other magnetic components. For a variety of applications, different material properties are desired. Therefore, ferrites materials having different compositions are used. To prevent electromagnetic interference, ferrite cores are employed to block low-frequency noise and absorb high-frequency noise. Spinel ferrites are used in transformer cores, microwave devices, and high-frequency devices in the electronics sector. If their dielectric loss is low, ferrite nanoparticles can be used in switching inductors, antenna rods, and microwave devices. Ferrites are an excellent option for both traditional and contemporary applications owing to their variety of shapes, ongoing breakthroughs in material characteristics and cost-effectiveness. In this chapter, the properties of ferrite nanoparticles are discussed, which play an essential role in making ferrite usable in the telecommunication industry, e.g., elastic properties, such as hysteresis, coercivity, and magnetic saturation. The usages of ferrites in various components of telecommunication equipments are also discussed, including filter circuits, broadband and core of transformers.
