Influences of pulverized particle size (0.67, 0.95, 1.14 and 1.39, μm) and magnetic field (0, 239, 478, 716 and 915kA/m) during compacting on the degree of alignment of Sr-ferrite were investigated using X-ray pole figure. Degrees of alignment of the compacted green bodies with average particle sizes of 0.95, 1.14 and 1.39 μm are saturated in a magnetic field of 239kA/m parallel to the compacting direction. To the contrary, applying the magnetic field perpendicular to the compacting direction, they are saturated in a magnetic field of 478kA/m. In the magnetic field lower than 478kA/m, degrees of alignment of the parallel configuration are higher than those of the perpendicular configuration, which is independent of particle size. In particular, at a small particle size of 0.67 μm, degree of alignment of the parallel configuration tends to be higher than that of the perpendicular configuration under any applied field.
