Spin-polarised neutron scattering has been used, to study the ferromagnetic structures of a pair of Fe90Zr10 metallic glass samples. These were made in Sheffield and in Budapest by conventional chill-block melt spinning, but under slightly different conditions. Neutron diffraction experiments at LAD, ISIS, confirm that the two samples are good metallic glasses and that they are in slightly different states of structural relaxation. The spin-dependent cross-sections were measured on the IN20 spectrometer, Institut Laue-Langevin. The Sheffield sample exhibits a large spin-flip cross-section, indicating the presence of non-collinear ferromagnetism. The Budapest sample has a much smaller spin-flip cross-section, consistent with a collinear ferromagnetic state. This suggests that non-collinear ferromagnetic structures may not be intrinsic to these glasses and that they are possibly stabilised in the absence of strain and/or by the surface topography.
