摘要
通过X射线衍射和磁性能测量的方法研究了金属间化合物RFe6.5Mn4Mo1.5(R=Y、Nd、Tb和Ho)的结构和磁性。所有这些化合物都具有单相ThMn12型结构,其晶格常数a、c和单胞体积V随原子序数的增加而减小。
The structure and magnetic properties of (R=Y、Nd、Tb and Ho )compounds are investigated by means of X-ray diffraction and magnetic measurements. All of the studied RFe_(6.5)Mn_4Mo_(1.5)compounds crystallize in the ThMn_(12) -type structure, which lattice constants and the unit-cell volumes decrease monotonously with increase of the atomic number for R=Nd, Tb and Ho. The Curie temperature and the saturation magnetization of these compounds were given in this paper.
