Fig. 1: Procedures for comprehensively obtaining spin textures by using group decomposition method involving three ingredients.
From: Unconventional spin textures emerging from a universal symmetry theory of spin-momentum locking
As an example, a compound with magnetic space group P31m1′ is considered with \({p}_{z}\) orbital located at Wyckoff position \(1a\) (top green boxes) around the Fermi level. The obtained \(k\cdot p\) Hamiltonian near the K point and the resultant Rashba spin texture are displayed in the bottom orange boxes.
