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

Figure 10

Intersections of the Fermi surface of ErGa₃ with planes 𝑘₃=const. Each square is bounded by the lines 𝑘₁=0, 𝑘₁=𝜋/𝑎, 𝑘₂=0, and 𝑘₂=𝜋/𝑎. The actual value of 𝑘₃ is given in the upper right corner. Solid line (green) b₁, broken line (red) b₂, dotted line (blue) b₃, and points connected by solid line (black) b₄. By virtually placing these squares in stacks one over the other, an insight into the various FSs is obtained.
