通过X射线和中子衍射、磁化强度、电阻率和磁阻测量，研究了(FeMn)3Si系统的磁性和结晶学性质。发现单相合金以L21A结构晶化，在低锰含量时具有铁磁性能。在较高浓度下，合金表现出更复杂的行为，在温度tR以下具有反铁磁性成分，而温度tR几乎与浓度无关。电阻率在tr和居里点都有异常。每个位置上磁矩的变化已被确定为浓度的函数，并根据由于添加锰而发生的环境变化进行了讨论。
Magnetic and crystallographic properties of the (FeMn)3Si system have been studied by X-ray and neutron diffraction magnetization resistivity and magnetoresistivity measurements. The single-phase alloys have been found to crystallize in the L21A structure and to have ferromagnetic properties at low Mn concentrations. At higher concentrations the alloys exhibit a more complex behaviour, having antiferromagnetic components below a temperature TR which is almost concentration independent. The resistivity showed anomalies at TR as well as at the Curie point. The variation of the magnetic moment on each site has been determined as a function of concentration and is discussed in terms of environmental changes occurring as a result of Mn additions.
