【Abstract】 Hexagonal magnetoplumbite-type ferrite magnetic powders such as BaFe 12 O 19 and SrFe 12 O 19 have attracted great attention not only as important permanent magnets but also as a promising material for perpendicular magnetic recording medium,because of their relatively strong anisotropy and interesting magnetization Various preparation methods have been used to obtain nanostructured ferrite magnetic powders,for example,chemical coprecipitation method,sol-gel method,hydrothermal method,mechanical ball milling method,glass crystallization method,organic resin method,liquid mix technique and so on In this paper,some of the recent research progress in synthesis of magnetoplumbite-type nanostructured ferrite magnetic powders is reviewed更多还原
