| Popis: | Substituted barium ferrite BaFe11−x−yCo0.5Ti0.5Ni x ZnyO19−r powders were prepared using a coprecipitation method and investigated by X-ray diffraction (XRD) and57Fe Mossbauer spectroscopy. The results show that the as-prepared magnetic powders possess the typical hexagonal structure and demonstrate both a good dispersibility and a narrow particle size distribution. The hyperfine fields for all sites decrease slightly asx (ory) increases. The Ni2+ ions prefer to occupy the 2a and 12k sites, and Zn2+ ions occupy the 4fIV site. |
