Figure 3. Orbital texture of p-derived bands in BiAg₂ without spin-orbit coupling.

(a–c) Arrows indicate the first principles values for the k-resolved in-plane orbital moment (OM) of the p-derived bands within the atom-centered approximation. The hexagonal Brillouin zone of BiAg₂ is indicated by thin black lines. In the vicinity of the Γ-point, the chirality of the OM texture is +1, 0, and −1 for p₋₁, p₀, and p₊₁, respectively. (d) The magnitude of the in-plane OM |m_n(k)| of the p-derived bands along the high-symmetry lines ΓM and ΓK.
