摘要
The contrasting magnetic structures of CeAuGe and CeAgCe are determined by neutron diffraction on powdered samples. In the case of CeAuGe, the magnetic peaks are found at the same positions in 2 theta as the nuclear peaks, confirming ferromagnetic ordering. The Ce moments lie within the ab-plane, and have a magnitude of mu(Ce) approximate to 1.1 mu(B). In the case of CeAgGe, the magnetic peaks can be indexed on the basis of a k = [1/3, 0, 0] propagation vector. Again the Ce moments lie within the nb-plane but with an increased magnetic moment of mu(Ce) approximate to 1.6 mu(B). (C) 2000 Elsevier Science B.V. All nights reserved.
