Magnetic ferrite powder, magnetic ferrite sinter, layered ferrite part, and process for producing layered ferrite part

摘要

Provided is magnetic ferrite powder in which a peak intensity ratio of Z phase (M₃Me₂Fe₂₄O₄₁: Mone or more kinds of alkaline-earth metal, Meone or more kinds from Co, Ni, Mn, Zn, Mg and Cu) of hexagonal ferrite is 30% or higher in X-ray diffraction and a peak value of a grain size distribution is in a range from 0.1 m to 3 m.
