Abstract

M-type ferrite Sr0.1Ca0.4La0.5Fe12O19 magnetic powders doped with CoxFe3-xO4 (0 ≤ x ≤ 1.25) in precursors were prepared by a ceramics process. The structure of specimens were examined by using an X-ray diffractometer. Only the magnetoplumbite phase was found in the specimens with the cobalt content (x) from 0.25 to 1.25 in precursor. The specimens exhibited a typical hexagonal M-type structure and the particles in specimens were uniformly distributed in size. The specimen with x=1.25 had the maximum saturation magnetization of 67.48 emu/g, while the residual magnetization and the coercivity of the specimen with x=1.00 reached the maximum value of 31.83 emu/g and 1270 Oe, respectively
