Ferrite calcined body, method for producing ferrite sintered magnet, and ferrite sintered magnet
The following steps are involved: a step of mixing raw material powders in such a manner that the values of 1-x-y, x and y in general formula Ca1-x-yLax(Sry'Ba1-y')yFe2n-zCoz, which shows the atom ratios of metal elements Ca, La, Sr, Ba, Fe and Co, fall within a zone enclosed by a coordinate point (a) (0.470, 0.297, 0.233), a coordinate point (b) (0.300, 0.392, 0.308), a coordinate point (c) (0.300, 0.300, 0.400), a coordinate point (d) (0.400, 0.200, 0.400) and a coordinate point (e) (0.470, 0.200, 0.330) in a (x, y, 1-x-y) triangular coordinate system and y', z, and the molar ratio (n) fulfil the formulae 0.5<=y'<=1, 0.2<=z<0.25 and 5.2
