Rashba-like states were observed, shifting to lower energies with increasing Ge content and dominating spin-dependent dispersions for x from 50% to 75%. These states exhibit pronounced asymmetry in both in-plane (sy) and out-of-plane (sz) spin polarizations for opposite ±k directions, arising from time-reversal and inversion symmetry breaking. Theoretical calculations confirmed this asymmetry along the K̄Γ¯K̄′ path. Constant energy maps reveal a pronounced sz spin component along Γ¯K̄, with a sign change crossing Γ¯M¯.
