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 2

Composition dependence of the lattice parameter of Eu(Cu_1 − xAg_x)₂Si₂ alloys. The maximum error in determining a and c does not exceed ±0.0006 nm in all cases: solid line—B-spline and blue dash dot line—direct line.
