摘要
讨论了利用分子场近似结合中子衍射或X射线衍射的实验结果计算R2 Fe17型稀土过渡族化合物中稀土磁矩与过渡族磁矩之间交换耦合常量的方法 ,并据此计算了R2 Fe17-xAlx(R =Tb ,Dy ,Ho ,Er,Gd ,x =7或 8)化合物中稀土磁矩与过渡族磁矩之间的交换耦合常量 .计算结果与实验值符合较好 .
A calculation of the exchange interaction constant between the R moment and the T moment in rare\|earth ( R ) transition\|metal ( T ) compounds of the type R 2Fe 17 has been discussed using molecular field theory combining with the results of neutron diffraction or X\|ray diffraction. The calculated values for R 2Fe 17- x Al x ( R =Tb,Dy,Ho,Er and Gd, x =7,8) have been given and they are in agreement with the experimental results .
