Electronic; magnetic and photoemission properties of the mixed-valence EuF3and EuCo2X2 compounds have been studied theoretically. Calculations have shown that europium is trivalent (4f6) in EuF3 compound. In EuCo2X2; the Eu is of intermediate valence Eu2.5+ (4f6.5). EuF3 compound is found nonmagnetic insulator. In EuCo2X2; only the europium is polarized magnetically. Photoemission (PE) measurements on EuF3 proved the exchange splitting of core s-type levels of europium even though it is in nonmagnetic (J = 0) state. The calculated exchange splitting of the Eu 4s and 5s states compares quantitatively well with the observed ones. © 2007 Elsevier B.V. All rights reserved;
