FERRITE MAGNET POWDER AND MAGNET USING THE MAGNET POWDER, AND METHOD FOR PREPARING THEM

The ferrite magnet powder of the present invention is magnet powder having, as the major phase, a La-Co magnetoplumbite ferrite where La and Co are substituted for Sr and Fe, respectively, represented by (1-x)SrO . (x/2)La2O3 . (n-y/2)Fe2O3 . yMO wherein x, y, and n represent mole ratios and satisfy...
