HemedaSeries of polycrystalline samples of Zn2-x Cux Ba Fe16 O27 were prepared by usual ceramic methods, where (x=0.0, 0.4, 0.6, 0.8, 1.0, 1.4) . X-ray analysis were obtained at room temperature using Coka with λ = 1.790A0 confirmed the presence of W-type hexaferrite phase structure . Saturation magnetization and hysteresis loops curves measurements at room temperature were studied as a … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Hot-Roll and Cold-Roll Byproduct-Derived Strontium Hard FerritesH. S. Woon, K. P. Lim, N. Puteri et al.Problem statement: Ceramic permanent magnets or more commonly known as strontium hexagonal ferrites have been widely used in permanent magnetic materials as they provide high remanence, high coercivity, relatively high energy product and good chemical stability. In this study, we treated factory byproduct from hot-roll and cold-roll steel industry was used as raw material in synthesis of strontium hexagonal hard … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,310 accessesView PDFCite
