REXS data from sample x = 0.041 taken at CHESS, A2. a and b show H,K maps T = 10 K around the nuclear (0, 0, 16) and magnetic (0, 1, 14) zones respectively. c H scan at (0, 1, 14) at 10 K exhibiting two IC peaks at (−0.003, 1, 14) and (0.006, 1, 14). d H scan at (−1, 0, 20) showing the two IC peaks split along the H direction 10 K and their absence at 190 K. IC peaks in c and d are both separated by 0.009 r.l.u. e The temperature dependence of the two IC peaks. Both IC peaks disappear at the same temperature TSDW = 182 ± 8 K. f Energy dependence of the IC peak at (0.006, 1, 14) and its comparison to the (0, 0, 16) charge peak. The solid lines in c–e are the fits to the data. Other than f, all data are collected at the energy of 11.217 keV. All vertical error bars in the figure represent 1 s.d. statistical errors
