Application of Calcium Hexaferrite as Microwave Absorbing Material: Review

Many studies have been conducted on Spinel, Garnet, and Hexa-ferrites in single multi-doped concentrations. This article is an attempt to review the researcher's work Ca, Ba, Sr hexaferrite by substituting a variety of various ions such as Al, La, Sn, Zr, Co, Cr, Ir. paper investigates M-type (Ca, Sr, Ba) with space group P63/mmc that were synthesized using techniques characterized XRD for crystallographic information, SEM TEM surface morphology, VSM magnetic behaviour, Vector Network Analyzer (VNA) microwave absorption properties. Changes material's chemical composition affect features coercivity, saturation magnetization, Curie temperature, well managing these properties utilizing compounds field industry.
