Magnetic susceptibility and high-field magnetization have been examined for the intermediate valence system EuNi2(Si1 - xGex)2. It was found that the compounds with 0.79 ≤ x ≤ 0.82 show a first-order valence transition under high magnetic field. The results are discussed in terms of the interconfigurational fluctuation (ICF) model.
