PROBLEM TO BE SOLVED: To provide strontium ferrite particles and powder which have ideal shapes and sizes for bonded magnet and moreover high saturation magnetization value σs.;SOLUTION: The strontium ferrite particles and powder have a composition expressed by (Sr1-xAx)O.n[Fe1-y-zCoyZnz)2O3] (where A denotes La, La-Nd, La-Pr, or La-Nd-Pr, n=5.80-6.10, x=0.1-0.5, y=0.0083-0.042, and 0≤z0.0168), the saturation magnetization value σs of ≥73 Am2/kg (73 emu/g), and a mean particle diameter of 1.0-3.0 μm. In addition, the particles and powder contain plate-like particles at a number ratio of ≥60%.;COPYRIGHT: (C)2002,JPO
