Extended Data Fig. 6: Nonmagnetic scattering channels for helical spin–momentum texture with different magnetization directions.

a, The upper panel shows that spins cant towards the c axis to generate a net c-axis magnetization. The lower panel shows that backscattering is allowed in all directions. b, c, To generate a net in-plane magnetization, the momentum of the band shifts perpendicular to the in-plane direction and the spins reorganize their directions (similar to the Edelstein effect31), as shown in the upper panels (the faded red arrows represent helical spin texture without magnetization for reference). The spins are still locked perpendicular to the original momentum centre31 (black circle). The lower panels show that backscattering is allowed only in the magnetization direction and forbidden in the perpendicular direction owing to spin reversal.
