X-ray photoemission spectroscopy and band structure calculation of cubic DyCu5

Abstract We report here on the in-phase component χ ′ of the AC-susceptibility at different frequencies for a single-phase cubic DyCu 5 sample with the lattice constant a=0.7027 nm . The valence band spectra of the compound were investigated by X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. Results of ab initio calculation of the electronic density of states using the tight-binding linear muffin-tin orbital (TB LMTO) method are compared with experimental data. We found a good agreement of the measured spectra with the results of numerical calculations.
