In this paper, the improvement of magnetic properties of anisotropic sintered ferrite with La-Co substitution was researched. The saturation magnetization and magnetocrystalline anisotropy field have been significantly improved by partial substitution of Co2+and La3+ion for Fe3+and Sr2+ion respectively in M-type sintered ferrite. Magnet was obtained with magnetic properties as follows: remanence Br=435mT, coercivity Hcb=318.5kA/m, intrinsic coercivity Hcj=366kA/m, and (BH)max=36.0kJ/m3.
