The present work purposes to prepare the Sm_2Fe_<17>N_X and Sm_2Fe_<17>C_xN_y magnet fine particles with an excellent magnetic property via the reactions between the vapor complexes of samarium-iron chloride and NH_3 or CH_4. The research term was 2 years, and last year (in 1992) we found that the nitride fine particles in the Sm-Fe system were partially produced by the thermal decomposition of Sm_mFe_nCl_<3(m+n)> vapor complexes in a NH_3-H_2 mixed gas. In this year, the carbide fine particles in the Sm-Fe system prepared in addition to the nitride fine particles above-mentioned, and the possibility of the preparation process for the Sm_2Fe_<17>N_X or Sm_2Fe_<17>C_xN_y magnet materials was studied by using the resulting fine particles as the raw materials.

本文的目的是通过钐-氯化铁的气相配合物与NH_3或CH_4的反应，制备具有优异磁性能的Sm_2Fe_<17>N_X和Sm_2Fe_<17>C_xN_y磁铁微粒。研究周期为2年，去年（1992年）发现Sm-Fe体系中的氮化微粒部分是由Sm_mFe_nCl_<3(m+n)>气相配合物在NH_3-H_2混合气体中热分解产生的。本年度，除上述氮化颗粒外，还制备了Sm-Fe体系中的碳化物细颗粒，并研究了以所得细颗粒为原料制备Sm_2Fe_<17>N_X或Sm_2Fe_<17>C_xN_y磁铁材料的可能性。
