FERRITE SINTERED MAGNET
The present invention provides a ferrite sintered magnet comprising ferrite crystal grains having a hexagonal structure, wherein the ferrite sintered magnet comprises metallic elements at an atomic ratio represented by formula (1). In formula (1), R is at least one element selected from the group consisting of Bi and rare-earth elements, and R comprises at least La. In formula (1), w, x, z and m satisfy formulae (2) to (5). The above-mentioned ferrite sintered magnet further has a coefficient of variation of a size of the crystal grains in a section parallel to a c axis of less than 45%.Ca1-w-xRwSrxFezCom (1)0.360≤w≤0.420 (2)0.110≤x≤0.173 (3)8.51≤z≤9.71 (4)0.208≤m≤0.269 (5)
