摘要：
The W-type hexagonal ferrites with the composition Sr1-x La (x) Co2Fe16O27 (0 <= x <= 0.35) magnetic powders were synthesized by the solid state method. The phase constituents, micro-morphology, and magnetic properties of the particles were investigated by x-ray diffraction (XRD), a scanning electron microscope, and a vibrating sample magnetometer. The single phase was observed in the W-type ferrites with different La content from XRD. The micro-morphology of the particles exhibits the hexagonal plate-like shape, and the particles are distributed homogeneously of W-type ferrites with different La content. The coercivity (H (c)) of the particles increases with the increase of La content (x), while the saturation magnetization (M (s)) of the particles first increases with x from 0 to 0.15, and then begins to decrease when x continues to increase.
