| description | To provide a novel ferrite sintered magnet that can be made to have a high coercive force without much reduction in residual flux density.SOLUTION: A ferrite sintered magnet 100 includes magnetoplumbite-type ferrite crystal particles 4 and a two-particle grain boundary 6a interposed between the ferrite crystal particles 4. The two-particle grain boundary contains Ca and La. The Ca/La atomic ratio in the two-particle grain boundary is 0.3 to 3.0.SELECTED DRAWING: Figure 1
【課題】残留磁束密度をあまり低下させずに保磁力を高くすることのできる新規なフェライト焼結磁石を提供する。【解決手段】マグネトプランバイト型フェライト結晶粒子４と、フェライト結晶粒子４間に介在する２粒子粒界６ａと、を備えるフェライト焼結磁石１００であって、２粒子粒界はＣａ及びＬａを含み、２粒子粒界におけるＣａ／Ｌａ原子比が０．３～３．０である、フェライト焼結磁石。【選択図】図１ |
