Fig. 2: Two-dimensional slices of the magnetic excitations in detwinned FeSe.
From: Spin correlations in the nematic quantum disordered state of FeSe
a–d Energy-vs-momentum slices of the magnetic excitations across Q = (1, 0), (0, 1) and (1, 1) measured with Ei = 147.5 meV at T = 5 K. e–n Constant-energy slices of the magnetic excitations, with Ei = 21 meV (e), 36 meV (f, g), 80 meV (h), 147.5 meV (i–j), and 295 meV (k–n) at based temperatures. For the Ei = 147.5 meV data (a–d), and (i, j), the scattering signal of an empty strain device with CYTOP has been subtracted as a background. A ∣Q∣-dependent background has been subtracted from the data shown in (e–h)20, and energy-dependent flat backgrounds are subtracted from the data (k–n).
