Fig. 2: Wave vector dependence of spin excitations in CeCu2Si2 as a function of energy.
From: High-energy magnetic excitations from heavy quasiparticles in CeCu2Si2
Constant-energy maps of the [H, H, L] plane for different energies are shown in the left panels, corresponding cuts along the [H, H, 1.48] direction obtained by binning data with 1.38 < L < 1.58 are shown in the middle panels, and corresponding cuts along the [0.22, 0.22, L] direction obtained by binning data with (0.17, 0.17) < (H, H) < (0.27, 0.27) are shown in the right panels. Data in this figure were measured using Ef = 5 meV. All vertical error bars represent statistical errors of 1 s.d.
