摘要（英）：

The invention relates to a soft magnetic ferrite material and a preparation method thereof. The soft magnetic ferrite material is characterized in that, its main components comprise, by mole part: 0.5-0.6mol of Al2O3, 49-51.5mol of Fe2O3, 6-6.5mol of ZnO, 25-25.5mol of MnO, 1.2-1.3mol of CuO, and 0.2-0.3mol of Ga2O3. The modification impurities added in the main components include, in terms of the weight ratios of the impurities to the soft magnetic ferrite material: 440-480ppm of B2O, 410-430ppm of La2O3, 360-380ppm of niobium carbide, 210-230ppm of As, 310-330ppm of tantalum carbide, 220-250ppm of Mo, 340-360ppm of SiO22, and 150-180ppm of V. The raw material formula of the soft magnetic ferrite material undergoes repeated optimization study research and optimization repeatedly, is scientific and reasonable, and is low in cost. Also, the magnetic permeability is high and the magnetic core loss is low.
