X-ray photoemission spectra measurements of CeNi2Sb2 and CeCu2Sb2



X-ray photoemission spectra, resistivity and susceptibility of CeNi2Sb2 and CeCu2Sb2 were measured and are discussed. The results indicate that these alloys are Kondo systems. For comparison of the valence band properties, the spectra of the isostructural alloys of RT2X2-type with R = La, Gd, T = Cu, Ni and X = Sn, Sb were investigated, too.
