<P>PROBLEM TO BE SOLVED: To provide a permanent magnet having temperature properties more excellent than those of an Nd<SB>2</SB>Fe<SB>14</SB>B based magnet, and having saturation magnetization higher than that of an Sm<SB>2</SB>Fe<SB>17</SB>N<SB>x</SB>bond magnet thus having excellent magnetic properties, to provide a method for producing the same, and to provide a permanent magnet material used therefor. <P>SOLUTION: The permanent magnet comprises MnBi powder and Sm<SB>2</SB>Fe<SB>17-x</SB>M<SB>x</SB>N<SB>y</SB>based magnet powder (wherein, M denotes at least one or more kinds selected from Mn, Co, Zr, Al, Ga, Ta, Nb and Ti), and in which the content of the MnBi lies in the range of 8 to 50 mass% of total weight. <P>COPYRIGHT: (C)2009,JPO&INPIT |
