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 1

Microstructure of Eu(Cu_1 − xAg_x)₂Si₂ alloys (magnification 600). Investigating was performed using a scanning electron microscope REMMA-102-02 (also, the quantitative and qualitative analysis of a composition). Note. The color coding of the number and composition of the samples assigns them to certain groups and will reveal itself as the article progresses.
