Fig. 6: Calculated band structure of monoatomic Ni wire.

a Without SOC and b with SOC for magnetization parallel to z axis (M//z) and c with SOC for M⊥z. The solid/dashed lines in a indicate the minority/majority-spin bands. The irreducible representation (labels in Figure) of the group C∞ν are displayed for minority-spin bands only. (adapted from ref. 45 with permission, copyright American Physical Society 2005).
