Effect of Cr3+ Doped on Structural, Magnetic and Electrical Properties of Sol-Gel Synthesized SrFe12O19 Hexaferrite Nanoparticles

Nanocrystalline SrFe 12-x Cr x O 19 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 SrFe 10 Cr 2 O 19 phase formation in the presence of non-magnetic (α-Fe 2 O...

Description
Summary:Nanocrystalline SrFe 12-x Cr x O 19 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 SrFe 10 Cr 2 O 19 phase formation in the presence of non-magnetic (α-Fe 2 O 3 ) 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.
