      Hexaferrite Sr1−xLaxFe12−x(Cu0.5Co0.5)xO19 (0 ≤ 𝑥 ≤ 0.50) magnetic powders and magnets were synthesized by the solid-state reaction method. The phase compositions of magnetic powders were investigated by X-ray diffraction. The single magnetoplumbite phase is obtained in magnetic powders with 𝑥 from 0 to 0.40. At 𝑥 = 0.50, CoFe2O4, and 𝛼-Fe2O3 were observed. The morphology of the materials was characterized by a field-emission scanning electron microscopy. The particles were hexagonal platelets. Magnetic properties of the materials were measured by a permanent magnetic measure equipment. The remanence of the materials increases with 𝑥 from 0 to 0.50. However, the intrinsic coercivity and magnetic induction coercivity of the materials increase with 𝑥 from 0 to 0.15, and decreases when 𝑥 varies from 0.15 to 0.50. Accordingly, the maximum energy product of the materials first increases with 𝑥 from 0 to 0.35, and then decreases when 𝑥 exceeds 0.35.
