Magneto-Structural Characterization of Strontium Substituted Lead Hexaferrite
In this work, the magnetic and structural properties of the system Pb1−xSrxFe12O19 (x = 0.1, 0.3, 0.5, 0.7 and 0.9) are reported. The samples were prepared by the traditional ceramic method. All the compounds are isostructural with the strontium hexaferrite (SrFe12O19). X-ray powder diffraction was...

| Sumario: | In this work, the magnetic and structural properties of the system Pb1−xSrxFe12O19 (x = 0.1, 0.3, 0.5, 0.7 and 0.9) are reported. The samples were prepared by the traditional ceramic method. All the compounds are isostructural with the strontium hexaferrite (SrFe12O19). X-ray powder diffraction was used to carry out the quantitative analysis of phases and to determinate the crystallographic parameters. It was found that the compound consists of only one phase and that the coercivity, remanence and saturation increased with the strontium content. The initial susceptibility was also obtained and results are discussed in terms of the magnetization mechanisms produced by the effect of the substitution on the hexaferrite. Furthermore, Néel temperature measurements indicate a strengthening of the exchange interactions with increasing strontium content. |
