Abstracts

EN

The crystal and electronic structure, magnetic and electric properties of intermetallic compounds Yb_{x}Gd_{1-x}Ni_{5} (x = 0.0, 0.2, 0.4, 0.5) are presented. The whole series crystallize in the hexagonal CaCu_{5} type of crystal structure. The ordering temperatures T_{C} and the effective magnetic moments decrease with increase in ytterbium concentration. The electronic structure studied by X-ray photelectron spectroscopy method shows the domination of Ni 3d states nearby the Fermi level. The multiplet structure visible in valence bands is typical of Yb^{3+} ions.
