Observation of the two-hole satellite in Cr and Fe metal by resonant photoemission at the2pabsorption energy

Electronic structure of YbGa1.15Si0.85and YbGaYamaoka1, Jarrige2, Tsujii3 et al. 2011Phys. Rev. B

“…The spectra obtained by resonant PES are comparable to those obtained by RXES, with both Raman-like and fluorescence-like (or Auger-like) spectral features at the absorption edge. [46][47][48][49] The intensity in Figs. 6(b) and 6(e) is normalized by the incident photon beam intensity.…”

Electronic structure and spectroscopy of the quaternary Heusler alloy Co2Cr1−xFexAl

“…An Auger signal with varying kinetic energy was not detectable. The differences in the resonant behaviour as well as the Auger emission are clearly related to the differences between the materials that is an alloy here compared to pure metals in [67]. Figure 8 shows the photon energy dependence of the valence band photo emission spectra taken with photon energies close to the Co L 3 edge.…”

“…Part of this very high intensity is, however, due to the intense underlying L 3 VV Auger electron emission. This type of feature was previously assigned as two-hole satellite [67] with varying two-hole correlation energy. Other than at the Cr and Fe edges, a clear resonance like behaviour is observed in the valence band spectra if crossing the Co L 3 absorption edge, especially at the Fermi energy.…”

Impurity states in the magnetic topological insulator V:(Bi,Sb)2Te3

“…In resPES, the valence band photoemission is enhanced by the resonant V 2p → 3d transition, i.e. in an element-specific way [41][42][43] . For comparison, similar PES spectra were measured at an energy below the absorption edge (hν OF F = 510 eV, "off-resonance").…”
