本文研究了一种具有体心四面体结构的硬磁合金的晶体结构和磁结构Mn1.074Al0.871C0.005中子衍射数据表明Mn 0.992、C 0.008占据（0，0，0）位，Mn 0.082、Al 0.871、C 0.047占据（1/2，1/2，1/2）位。锰原子的磁矩沿着c轴，两个位置指向相反的方向。与Mn1.09Al0.91合金的磁性能和力学性能相比，MnAlC合金的磁性能和力学性能得到了显著提高。
The crystal and magnetic structure of the hard magnetic alloy Mn1.074Al0.871C0.005, which has a body centered tetragonal structure, has been investigated. Neutron diffraction data shows that Mn0.992, C0.008 occupy the (0,0,0) site and Mn0.082, Al0.871, C0.047 occupy the ( 1/2 , 1/2 , 1/2 ) site. The magnetic moments of manganese atoms are along the c axis, pointing in opposite directions for the two sites. Comparing these results with those of Mn1.09Al0.91, the significant improvement of magnetic and mechanical properties in the ternary alloy MnAlC is explained.
