Abstract

Abstract: Nanocrystalline SrFe12-x Crx O19 hexaferrite particles were successfully synthesized via Sol-gel route from Sr 3+ and Fe 3+ nitrates at molar ratio of 1:9 (Fe/Sr). The XRD results revealed single hexagonal magnetoplumbite SrFe10 Cr2 O19 phase formation in the presence of non-magnetic (α-Fe2 O3 ) phases in the heated samples. The dielectric properties as a function of frequency under normal conditions were also measured in the frequency range of 500 Hz to 1 MHz. The variations of dielectric constant are discus on the basis of Maxwell–Wagner and Koops models. In VSM graph, coercivity and saturation magnetization confirms that the synthesized materials are suitable for applications in magnetic recording media.
