FERRITE SINTERED MAGNET, FERRITE PARTICLES, BONDED MAGNET, MOTOR, AND GENERATOR

NAGAOKA JUNNICHI / TAGUCHI HITOSHI / SUGAWARA YUICHI / SATO JO

Provided is a ferrite sintered magnet including a ferrite phase having a magnetoplumbite-type crystal structure. x, y, and m satisfy the following Equations (1), (2), and (3) when composition of the ferrite sintered magnet is represented by R1-xAxFem-yCoy, where R denotes at least one kind of element selected from rare earth elements including Y and A denotes Ca or Ca and elements including at least one kind selected from Sr or Ba. The content of B in the ferrite sintered magnet is from 0.1% to 0.6% by mass in terms of B2O3.0.2≤x≤0.8 (1)0.1≤y≤0.65 (2)3≤m≤14 (3)
