Fig. 3

REXS data from sample x = 0.04 collected at 6-ID-B. a, b H,K maps at the (0, 0, 16) and (0, 1, 14) zones at T = 10 K. c H scans at select (0, 1, 4N + 2) (N = 2, 3, 4) magnetic zone centers at 10 K collected both in the σ–π channel and the σ–σ channel. Solid lines are fits to the data with three Lorentzian peaks, which are individually represented by blue tan and cyan shaded areas. Data collected at different zones and in different channels are offset for comparison. d L scans at the commensurate (0, 1, 14) and incommensurate (−0.0035, 1, 14) positions at 10 K (solid symbols) and at 200 K (empty symbols). The solid lines are fits to the data with a single Lorentzian peak and the dashed line denotes the instrumental resolution. e Energy scans at the commensurate and incommensurate peak positions. Data are offset for clarity. f K scan at (1, 0, 10) at T = 10 K after the sample was rotated counter-clockwise by 90°. The inset shows the H,K map about the (1, 0, 10) position and the magenta line denotes the scan direction in the main panel. No splitting along K is observed, and additional analysis suggests a splitting still occurs along the H direction (Supplementary Figure 3(b–f)). Other than (e), all data are collected at the energy of 11.214 keV. All vertical error bars in the figure represent 1 s.d. statistical errors
