Abstract

To design materials possessing high-quality persistent spin textures (PSTs), both the spin lifetime (τ_s) and portion of the Brillouin zone exhibiting the PST (S) require optimization. We find τ_s and S are optimal with moderate spin-orbit coupling (SOC) parameters. Furthermore, τ_s and S can be tuned by the magnitude of the BX₆ octahedral rotations in perovskite-derived materials, which governs the PST in a manner opposite to that from intrinsic SOC (Δ_SOC), enabling discovery of optimal PST materials with strong SOC.
