Abstract

The electronic structure of the ternary ErNi4B compound, crystallizing in hexagonal CeCo4B structure (P6/mmm space group) was studied by X-ray photoelectron spectroscopy (XPS) and ab initio calculations. Core levels and valence band were investigated. The valence band of the XPS spectra is determined mainly by the Ni(3d) and Er(4f) bands. The peak positions are in good agreement with the binding energies of a metallic erbium and nickel. The experimental valence band spectrum as well as the calculated density of states show a domination of the Ni(3d) states in region from −4eV to the Fermi level.
