  • Sintered magnet and method for production thereof
    Publication number: 20060145118
    Abstract: The present invention relates to a sintered magnet, which has one Curie temperature and comprises the primary phase of a hexagonal ferrite in chemical formula A1-xMxFe12 -yRyO19, wherein A represents at least one element selected from Sr, Ba and Ca, M represents at least one element selected from the group consisting of rare earth elements and Bi, and must contain La as essential component, R represents at least one element selected from Co, Mn, Zn, Ge and As, and must contain Co as essential component, and the chemical valence of Co is +3, the subscript x and y are the molar ratio, 0?x?0.5, 0?y?0.5, x and y are not zero at the same time. The present invention provides another sintered magnet, which has one Curie temperature and comprises the primary phase of a hexagonal ferrite in chemical formula A1.
