(a–i) Constant-energy cuts through the stripe and Néel magnetic wavevectors along the K direction at 4 and 110 K. (j–r) Constant-energy cuts through the Néel magnetic wavevector Q=(1, 1) along the transverse direction. The scan directions are marked by the arrows in the insets. The peak positions (dispersions) are determined by fitting with Gaussian profiles convoluted with the instrumental resolution, with the Fe²⁺ magnetic form factor corrected. The fitted dispersions are shown in Fig. 2. The error bars indicate 1 s.d.
