Nanoferrites have attracted a great deal of attention in the field of electromagnetic wave suppression for more than threedecades. Ferrites are used as an umbrella term for various classes of iron oxides. These oxides of iron exhibit varying crystal structures and hence varying magnetic and electromagnetic properties. As appealing as they are when used in the megahertz frequency range for electromagnetic wave suppression, their magnetic property decays toward the upper gigahertz frequency range due to the Snoek's limit. To combat that, various strategies have been researched upon including doping with other metals and conjugation with carbonaceous and other types of conducting nanomaterials. This chapter comprehensively discusses the various types of ferrites that have been popularly used in literature over the past decade as well as the modifications made to them so that their electromagnetic wave shielding properties can be extended over a wider frequency window. © 2023 Elsevier Inc.
