我们报道了用自旋相关的康普顿散射结合从头算电子结构计算来研究单晶NbFe中的自旋矩。从实验中我们发现，总的自旋矩是。将测量的自旋密度与线性松饼锡轨道计算的理论结果相比较，确定存在铁磁矩的非铁磁排列，2Fe位与体磁矩反平行排列。在NB站点上有一个小的力矩，也与净力矩相反。轨道矩已被确定为。
We report a study of the spin moment in single crystal NbFewithusing spin-dependent Compton scattering in conjunction withab initioelectronic structure calculations. From the experiment, we find that the total spin moment is. Comparison of the measured spin density with theoretical results from linearized muffin-tin orbital calculations determines there to be aferrimagneticarrangement of Fe moments, with the 2Fe site aligned antiparallel to the bulk moment. There is a small moment on the Nb site, also antiparallel to the net moment. The orbital moment has been determined to be.
