Sm-Fe-N bulk magnets produced by compression shearing method

Magnetic Sm-Fe-N powder was successfully consolidated into bulk material at room temperature by the compression shearing method. The bulk material retained the original Sm2Fe17N3 phase structure without any appreciable decomposition of the Sm2Fe17N3 phase. The resultant bulk Sm-Fe-N magnet showed a higher coercivity value than the original Sm-Fe-N powder.
