Notes:
Measuring the valence band density of states (DOS) of Fe provides a stringent test of models of metallic ferromagnetism at finite temperatures. The density of states of Fe above the Curie temperature TC, as obtained by self-consistent calculations in the disordered local moment (DLM) picture by Oguchi et al. and Pindor et al. differs strongly from the T=0 DOS calculated by Moruzzi et al. between the Fermi energy and 2-eV binding energy, i.e., the relatively broad peak in the T=0 DOS around 1-eV binding energy is of much smaller amplitude in the T(approximately-greater-than)TC DOS. This effect should be observable by valence band XPS on Fe as a 30% decrease of intensity at about 1-eV binding energy with a typical energy resolution of about 0.8 eV. We have measured the valence band XPS of Fe(100) at room temperature and temperatures above TC. The predicted intensity decrease has not been observed.
