a Background subtracted scan along (H,0,0) in the spin-flip (SFX) channel. The magnetic intensity appears as a Gaussian signal centered at (0.5,0,0). b Background subtracted scan along (H,0,0) in the non-spin-flip (NSFX) channel showing the nuclear scattering from the (Ortho-VIII) type chains superstructure. c Scan along Q = (H,0.5,0) obtained through XYZ polarization analysis (XYZ-PA) showing a magnetic signal centered at H = 0. d Background subtracted scan along Q = (0.5,0,L) in the spin-flip (SFX) channel. The magnetic intensity appears as a Gaussian signal centered at (0.5,0,0). e Magnetic intensity resulting from XYZ-PA at different wave-vectors in the reciprocal space: (0.5,0,0), (0.5,1,0) and (1.5,0,0). f 3D representation of the reciprocal space showing the momentum scans performed in a–d. Data in a, b, d, e were measured on IN22 at 1.6K with the sample aligned in the (1,0,0)/(0,0,1) scattering plane. Data in c were measured on 4F1 at 4K with the sample aligned in the (1,0,0)/(0,1,0) scattering plane. Lines are fits by a sum of Gaussian peaks to the data. Error bars represent one standard deviation. Raw data are given in Supplementary Fig. 3.
