Patent ID: 7563330

Claim:
A manufacturing method of a magnetic material, comprising: preparing a powder raw material by mixing at least two of powders selected from a powder A, a powder B, a powder C, and a powder D, where the powder A is at least one selected from an elemental powder of element R, and the element R is at least one selected from Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb, the powder B is at least one selected from an elemental powder of element T, and the element T is at least one selected from Fe, Co, Ni, Mn, and Cr, the powder C is at least one selected from an elemental powder of element M, and the element M is at least one selected from Si, B, C, Ge, Al, Ga, and In, and the powder D is at least one selected from compound powders composed of at least two of elements among the element R, the element T, and the element M; and forming a sintered body of the magnetic material having an NaZn 13 crystal structure phase by heating the powder raw material while applying a pressure.
