Abstract

This chapter delves into the fascinating world of nanohexaferrites and their pivotal role in the development of advanced gyromagnetic devices. Hexaferrites, also known as ferrites, are magnetic materials with a hexagonal crystal structure, offering remarkable magnetic properties attributed to their unique crystalline structures. This chapter comprehensively explores the synthesis techniques for nanohexaferrites, encompassing coprecipitation, sol–gel, hydrothermal and microwave-assisted methods, enabling precise control over size and composition. With a strong emphasis on applications, this chapter highlights nanohexaferrites' significance in resonance isolators, microwave devices, radar systems and permanent magnets. These materials exhibit exceptional properties, such as high saturation magnetization, low insertion loss and high isolation, making them indispensable in diverse industries. The promising potential of nanohexaferrites in emerging technologies, their cost-effectiveness and sustainability in a changing materials landscape are also discussed. This chapter serves as a valuable resource for researchers, engineers and enthusiasts in the field of magnetic materials and their applications, offering insights into the synthesis, properties and different applications of nanohexaferrites in gyromagnetic devices.
