Abstract This article discusses the recently intensified studies on the ThMn 12 -type hard magnetic compounds. Among the important developments were the synthesis of compounds superior to the Nd 2 Fe 14 B in saturation magnetization, the increased interest on Ce-substituted and rare-earth-free compounds and also the emergence of mechanochemistry as a method for manufacturing anisotropic powders with high coercivity. The theoretical studies might have had a greater impact if more attention was paid to the structural stability of these compounds. Little information is available on the fabrication of dense three-dimensional magnets; these efforts must be intensified for a successful implementation of the most advanced RFe 12 -type materials.

用于永磁体的 RFe 12 型化合物的最新进展

摘要 本文讨论了近年来对ThMn 12 型硬磁化合物的深入研究。重要的进展包括合成在饱和磁化强度方面优于 Nd 2 Fe 14 B 的化合物，对 Ce 取代和不含稀土的化合物的兴趣增加，以及机械化学作为制造具有高的各向异性粉末的方法的出现。矫顽力。如果更多地关注这些化合物的结构稳定性，理论研究可能会产生更大的影响。关于制造致密三维磁体的信息很少；为了成功实施最先进的 RFe 12 型材料，必须加强这些努力。
