Electronic Structure of the Cubic Compounds ReGa₃ (Re = Er, Tm, Yb, and Lu)

Figure 2

Left panel: Band structure of LuGa₃ with lattice constant 𝑎=4.212 Å. 𝐸_𝐹=2.059387 Ryd. The horizontal line at 1.4712 Ryd denotes the 4f bands. Black line: Δ₁,𝑍₁,Σ₁,Λ₁,𝑇₁ representations, red line: Δ₂,.₂,Σ₂,Λ₂,𝑇₂ representations, green line: Δ^′₂,𝑍₃,Σ₃,Λ₃,𝑇^′₂ representations, blue line: Δ₅,𝑍₄,Σ₄,𝑇₅ representations. Right panel: density of states in units of electronscell^(-1) Ryd^(-1), dashed line denotes the position of the Fermi level. Figure 3 illustrates the position of the symmetry points and of the lines within the BZ.
