对Nd_(15)Fe_(85-x)B_x(x=0-8)合金作了Mossbauer分析及磁测量,探讨了硼含量对结构的影响。 对于最佳磁性能的Nd_(15)Fe_(77)B_8合金,其Mossbauer谱可分解为6套铁磁亚谱和一套顺磁亚谱,分别对应于Nd_2Fe_(14)B四方相和富Nd相,并估计有6％的Fe原子处于富Nd相中。
Mossbauer spectra and magnetic properties for Nd_(15)Fe_(85-x)B_x (x=0-8) alloys have been measured. The effect of B content on structure of the alloys has been discussed. The Mossbauer spectrum for Nd_(15)Fe_(77)B_8 alloy with the best magnetic performance can be considered as the superposition of 6 ferromagnetic subspectra for Nd_2Fe_(14)B phase and a paramagnetic subspectrum for Nd-rich phase. It can bc estimated that there are 6% of Fe atoms in the Nd-rich phase.
