In this study, M kind of hexaferrite strontium with the formula of SrFe12-x(ZrCo0.5M0.5)0.5XO19 by Sol-Gel self-combustion in pH=7 was synthesized and the influence of substitution of iron (III) ions by M= Mn2+ with various amounts (x=0.2, 1, 1.8) was investigated. In addition, structural features, bond situation, particles morphology and electromagnetic traits of frail product were studied by using X-ray powder, diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Field Emission Scanning Electron Microscopes (FE-SEM) and Value Stream Mapping (VSM) analysis. The result of XRD showed the 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 the amount of X increased. Therefore, the optimal level of magnetism for the sample of magnesium will be in X=0.4 and Hc reduced by enhancing X from 0.2 to 1.6 which showed that the prepared nanoparticle became softer as the amount of X increased.
