Electron Transport Properties of Eu(Cu_1 − xAg_x)₂Si₂ (0 ≤ x ≤ 1): Initiation of Transition Eu²⁺ ↔ Eu^2.41+ in the Intermediate Valence State

Figure 5

The effective valence of Eu ion (probability p₃₊ presence in Eu³⁺ state) depending on the excitation energy, for different temperatures, is calculated in the frame of the ionic model of interconfigurational fluctuations [11].
