<P>PROBLEM TO BE SOLVED: To provide an NdFeB-based magnet material which can reliably have coercivity equal to or higher than that of a magnet containing a rare metal such as Dy, Tb, Co and Cr, without containing a large amount of these rare metals. <P>SOLUTION: The NdFeBCu magnet material is formed of a liquid-quenched ribbon of Nd-Fe-B-Cu<SB>X</SB>(x is a number which represents an atomic number ratio and satisfies 1≤x≤3). <P>COPYRIGHT: (C)2010,JPO&INPIT |
