| Abstract | Gd5SixGe4−x (0≤x≤0.9) has been studied using neutron powder diffraction at a wavelength of 2.3724 Å. Antiferromagnetic ordering of the full 7 µB Gd moments in the Pnm'a magnetic space group is seen for Gd5Ge4, with the moments predominantly parallel to the c axis, with a significant a-axis component at the Gd 8d2 site. The remarkably strong (010) antiferromagnetic reflection has been used to map out the structural and magnetic phase diagram for this system and show that the O(II)→O(I) structural transformation never proceeds to completion in zero field. The absence of scattering that could be attributed to long-range FM order in the O(I) modification suggests that an externally applied field may be needed to stabilize the ferromagnetic state. |
