It is believed that the mechanical al-loying by high power ball milling and the grain size down to about tens of nm are most effi-cient approach to prepare such magnet. The occurrence of some soft magnetic phases seemsto lead to the shoulder on the demagnetization curves. Key words:  Sm-Fe-N magnet      mechanical alloying      nitriding      annealing      Received:  18 March 1993      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1993/V29/I3/80 1 Sun H, Coey J M D, Otani Y, Hurley D P F, J Phys: Condens.
