Zusammenfassung:	This rare earth ferrite particle is represented by formula (1): Ln2xFe2(1-x)O3 (in formula (1), Ln represents a rare earth element selected from the group consisting of lanthanum, praseodymium, neodymium, and yttrium, and x represents a number not less than 0.45 but less than 1.00), and has a 50%-diameter (d50) of 0.50 μm or less in a volume-based cumulative distribution in the particle size distribution. Cette particule de ferrite de terres rares est représentée par la formule (1) : Ln2xFe2(1-x)O3. Dans la Formule (1), Ln représente un élément de terres rares choisi dans le groupe constitué par le lanthane, le praséodyme, le néodyme et l'yttrium, et x représente un nombre non inférieur à 0,45 mais inférieur à 1,00. Ladite particule a un diamètre de 50 % (d50) de 0,50 µm ou moins dans une distribution cumulative basée sur le volume dans la distribution de taille de particule. 式（１）：Ｌｎ２ｘＦｅ２（１－ｘ）Ｏ３　（１）（式（１）中、Ｌｎは、ランタン、プラセオジム、ネオジム、及びイットリウムからなる群より選択される希土類元素であり、ｘは、０．４５以上１．００未満の数である。）で表され、かつ、粒度分布の体積積算分布における５０％径（ｄ５０）が０．５０μｍ以下である、希土類フェライト粒子。
