Figure 6: Band structures and Fermi surface of BaBi3.
From: Spin-orbit coupling enhanced superconductivity in Bi-rich compounds ABi3 (A = Sr and Ba)

(a) The band dispersion of BaBi3 with (the red lines) and without (grey lines) SOC. (b–e) are the Fermi surface of BaBi3 with SOC, while (f–i) are those without SOC. The blue arrows in (i) denotes the nesting vectors M and R.
