(57) [Abstract] (Correction) [Problem] Spindle-shaped goethite particle powder having a uniform particle size and no mixed dendritic particles, and having an appropriate particle shape and a large axial ratio. Provided is a spindle-shaped metallic magnetic particle powder containing iron as a main component, which has a high coercive force and an excellent coercive force distribution, which is obtained by using the spindle-shaped goethite particle powder as a starting material. A spindle-shaped particle having an average major axis diameter of 0.05 to 1.0 μm, the particle including a seed crystal portion and a surface layer portion, wherein the seed crystal portion contains Co based on total Fe. 0.5 ~ 25 atomic% is contained, and the surface layer portion contains Al as a whole. Spindle-shaped goethite particle powder comprising goethite particles in an amount of 0.5 to 15 atom% with respect to e. |
