【Abstract】 The effects of light rare earth substituting Sm on the magnetic property and thermal stability of 2:17 type permanent magnet are reported.The results show that replacing Sm with light rare earth in the 2:17 type permanent magnet will improve the B r and (BH) max of the material,but the substitution amount should be less than 0 3,otherwise,the intrinsic coercivity will drop sharply,and we can’t get the practical magnet.更多还原
