Abstract
La présente invention concerne une poudre de ferrite qui contient 0,9% en masse à 2,5% en masse de lithium (Li), 1,0% en masse à 8,0% en masse de manganèse (Mn), et 58,0% en masse à 69,5% en masse de fer (Fe), et a une phase cristalline appartenant au groupe spatial P4132 et une phase cristalline appartenant au groupe spatial Fd-3m. Dans le profil de diffraction des rayons X, la demi-largeur du plan (311) de la phase cristalline appartenant au groupe spatial Fd-3m est de 0,09° à 0,22°, et le diamètre de particule moyen en volume D50 n'est pas inférieur à 1 µm mais inférieur à 20 µm.
