摘　　要：在中子三轴谱仪上用粉末中子衍射测定室温下ＹＦｅ１０Ｍｏ２Ｎ０．７５的晶体结构和磁结构，衍射数据用ＦＵＬＬＰＲＯＦ轮廓精修程序进行处理，确定了替代原子Ｍｏ和间隙原子Ｎ的占位以及磁性原子Ｆｅ的原子磁矩。并讨论了磁结构对内禀磁性能的影响。The crystallographic and magnetic structure of YFe 10 Mo 2N 0 75 was studied by the powder neutron diffraction technique using a neutron triple-axia spectrometer at room temperature. The fractional occupancies of Mo and N atoms and the magnetic moments of Fe atoms were obtained by Rietveld analysis program FULLPROF. The intrinsic magnetic properties were discussed.
