<p>A ferrite magnet, characterized in that it comprises a magneto-plumbite single phase represented by the formula: (Sr1-xAx)O.n[(Fe<3+>1-y Mg<2+>y)2O3], wherein A is at least one selected from among rare earth elements, x, y and n represent a mole ratio, and 0 < x <= 0.6, 0 < y <= 0.05 and 6.0 < n <= 6.6; and a method for producing the ferrite magnet which comprises weighing respective raw material powders of SrCO3, Fe2O3, A2O3 and MgO, mixing them, calcinating the resultant mixture in a reducing atmosphere or in air to prepare a mixed powder, subjecting the mixed powder to a wet or dry forming to prepare a formed product, and sintering the formed product in a reducing atmosphere, to thereby form the magneto-plumbite single phase represented by the formula: (Sr1-xAx)O.n[(Fe<3+>1-y Mg<2+>y)2O3].</p> |
