Recently, with the quick evolution of electronic technologies, and the development of telecommunication, high-performance microwave absorbing composites in which ferrite is one of their components have attracted a lot of attention. These composites should have high absorption intensity, a wide absorption bandwidth, a thin thickness, and finally light weightiness. These composites often exhibit efficiency to fulfill coveted magnetic and dielectric characteristics. This review provides a brief presentation of ferrites and among them are spinel ferrites and hexagonal ferrites. In addition to that, it discusses the classifications of ferrites according to magnetic properties, the synthesis methods to prepare nano ferrites, and control their properties. Also, it presents the main mechanism to absorb the microwaves (e.g. dielectric and magnetic losses) and finally discusses the microwave absorbing characteristics of ferrites and their composites in terms of matching frequency, reflection loss (RL) values, and absorption bandwidth.
