Abstract
We examined the temperature dependence of the Eu valence in La0.9Eu0.1Ni2(Si1−xGex)2 by means of magnetic susceptibility measurements and X-ray absorption spectroscopy. It was found that the Eu ions are in the intermediate valence state for 0.2≤x≤0.8 and the Eu valence gradually varies with temperature. The results are compared with those of the concentrated EuNi2(Si1−yGey)2 compounds. The main factor in determining the Eu valence in both dilute and concentrated alloys is discussed.
