A multipolar k·p theory for C3v crystals reveals band-dependent total-angular-momentum textures with vorticities |W_n|=1,2,5 that produce nonmonotonic current-induced spin polarization responses.
Other param- eters are J0 = N0max(|⟨ˆJ (1/ 2 y ⟩|), χ 0 = N0 max(|⟨χ (1/ 2 xy ⟩|) where N0 = eτ / (2π )2 and EF = µ 1
