本文详细报道了用粉末和单晶中子衍射研究Néel温度K以下磁序的结果。可以清楚地区分两种不同的磁有序相。在最低温度下，发现了具有传播矢量的公度磁结构，而中间相（K）的特征在于具有公度磁结构。磁性结构与所有其他已知的化合物（=稀土元素）形成鲜明对比，可能是由于Yb状态的一些巡回性导致了磁性。
We report on the results of powder and single-crystal neutron diffraction to investigate the magnetic order inbelow the Néel temperatureK in detail. Two different magnetically ordered phases can clearly be distinguished. At lowest temperatures a commensurate magnetic structure with a propagation vectoris found, while the intermediate phase (K) is characterized by an incommensurate magnetic structure with. The magnetic structure inis in marked contrast to all other knowncompounds (= rare earth element) likely due to some itineracy of the Ybstates being responsible for the magnetism.
