N2 - To design materials possessing high-quality persistent spin textures (PSTs), both the spin lifetime (τs) and portion of the Brillouin zone exhibiting the PST (S) require optimization. We find τs and S are optimal with moderate spin-orbit coupling (SOC) parameters. Furthermore, τs 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 (ΔSOC), enabling discovery of optimal PST materials with strong SOC.
