Abstract :
In this study, M kind of hexaferrite strontium with the formula of SrFe12-x(ZrCo0.5M0.5)0.5XO19by Sol-Gel self-combustion in pH=7 was synthesized and the influence of substitution of iron (III) ionsby M= Mn2+ with various amounts (x=0.2, 1, 1.8) was investigated. In addition, structural features, bondsituation, particles morphology and electromagnetic traits of frail product were studied by using X-raypowder, diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Field Emission ScanningElectron Microscopes (FE-SEM) and Value Stream Mapping (VSM) analysis. The result of XRD showedthe formation of hexaferrite strontium phase and (VSM) analysis illustrates the amount of (Ms) and (Mr)increased in comparison with pure sample and it can be seen that (Ms) and (Mr) reduced when theamount of X increased. Therefore, the optimal level of magnetism for the sample of magnesium will bein X=0.4 and Hc reduced by enhancing X from 0.2 to 1.6 which showed that the prepared nanoparticlebecame softer as the amount of X increased.
