From: Observation of momentum-dependent charge density wave gap in a layered antiferromagnet \({\textrm{Gd}}{\textrm{Te}}_{3}\)

Figure 4

Momentum dependence of the gap. (a) FS measured with photon energy of \(\mathrm {68~eV}\) with colored lines representing the cuts at color-coded angles. The angles are taken with respect to the \(\mathrm{\overline{Z}}-{\overline{\Gamma}}-\mathrm{\overline{Z}}\) direction. (b) Shift in the fitted Fermi edge on going away from \(\mathrm{\overline{Z}}-{\overline{\Gamma}}-\mathrm{\overline{Z}}\). (c) Gap below the Fermi level plotted against the angle from the \(\mathrm{\overline{Z}}-{\overline{\Gamma}}-\mathrm{\overline{Z}}\) direction. Data were collected at the SSRL beamline 5-2 at a temperature of \(\mathrm {8~K}\).
