Ferrite sintered magnet
A ferrite sintered magnet contains metal elements according to an atomic ratio represented by a formula (1): Ca<1-w-x>RSrFeCo; in the formula (1), R represents at least one element of rareearth elements and Bi; R at least comprises La; in the formula (1), w, x, z, and m satisfy following formulas (2)-(5): (2) 0.360<=w<=0.420; (3) 0.110<=x<=0.173; (4) 8.51<=z<=9.71; and (5) 0.208<=m<=0.269. In a cross section parallel to an easily magnetized shaft, the number of total ferrite grains is set to be N, the number of ferrite grains having lamination defects is set to be n, and 0<=n/N<=0.20.
该铁氧体烧结磁铁以下述式(1)所示的原子比含有金属元素，CaRSrFeCo···(1)，式(1)中，R为选自稀土元素和Bi中的至少一种元素，R至少包含La，式(1)中，w、x、z和m满足下述式(2)～(5)：0.360≤w≤0.420···(2)；0.110≤x≤0.173···(3)；8.51≤z≤9.71···(4)；0.208≤m≤0.269···(5)，在与易磁化轴平行的截面中，将总铁氧体晶粒的数量设为N、将具有层叠缺陷的铁氧体晶粒的数量设为n时，满足0≤n/N≤0.20。
