| Popis: | The nature of the electron state band in the amorphous metal alloys CuHf and CuZr has been studied using synchrotron radiation as a source in photoemission experiments. In the photon energy range - 45 eV the valence band undergoes resonant photoemission which emphasizes Hf 5d-like states in CuHf and Zr 4d-like states in CuZr, while at higher photon energies contributions from these states are strongly de-emphasized because of Cooper minima in their cross-sections. The ratio of the intensities of the valence band as compared with other peaks in the spectrum characteristic of Cu or Hf (Zr) shows that the near-Fermi-level region is not wholly Hf (Zr) d-like in character, but that the degree of hybridization of these states is less than in alloys such as FeZr where both elements have partially filled shells. |
