Figure 1

High resolution photoemission data from $\mathrm{Au}\left(111\right)$ measured with the channeltron detector of the COPHEE spectrometer using linearly polarized light at $\hslash \omega =21.1\mathrm{eV}$. (a) Fermi surface map, (b) dispersion map. The measured intensities are shown in a linear grey scale where white is the highest intensity. The spin structure predicted from a nearly free-electron model is indicated by arrows.Reuse & Permissions

Figure 2

(Color online) Spin-resolved photoemission spectra from the $\mathrm{Au}\left(111\right)$ surface state at various polar emission angles. The photon energy was $\hslash \omega =21.1\mathrm{eV}$. Details of the analysis are given. The spin assignment was determined from the transverse in-plane component of the polarization vector. Spin-up and spin-down intensities are marked with filled and open triangles, respectively.Reuse & Permissions

(Color online) Measured spin-resolved momentum distribution curves at $E_B=170\mathrm{meV}$ using UV-light of $\hslash \omega =21.1\mathrm{eV}$ (a) in the $\overline{\Gamma }-\overline{M}$ and (b) $\overline{\Gamma }-\overline{K}$ azimuth. The lower part of each panel shows the measured polarization components for in-plane (transverse) and out-of-plane polarization, respectively.Reuse & Permissions

Figure 4

(Color) Measured spin-resolved momentum distribution maps for $E_B=170\mathrm{meV}$ using UV-light of $\hslash \omega =21.1\mathrm{eV}$. The top panel (a) shows the total intensity map and a sketch of the Fermi surface and the predicted spin structure. Purple arrows indicate the projection axes for in-plane polarization. The center panels (b) and (c) show the polarization maps in a color-scale representation (b) for the in-plane component and (c) for the out-of-plane component of the polarization vector. The in-plane polarization (b) is a projection on the tangents to the circular Fermi surface. Red (blue) indicates a counterclockwise (clockwise) spin orientation. The bottom panels show the individual spin-up and-spin down intensity maps derived from (a) and (b). Note the different radii of the two Fermi surfaces of the individual bands. These data consisting of 1080 angular settings were measured in $7\mathrm{h}$ including a $1\mathrm{h}$ break as the beam in the electron storage ring was lost (black blot in the intensity maps). The shift of $\overline{\Gamma }$ with respect to the center of the graphs is due to a $0.5°$ misalignment of the sample rotation axis. No symmetrization techniques have been used in the representation of these maps.Reuse & Permissions
