Unconventional spin textures emerging from a universal symmetry theory of spin-momentum locking

Abstract Spin textures, i.e., the distribution of spin polarization vectors in reciprocal space, exhibit diverse patterns determined by symmetry constraints, resulting in a variety of spintronic phenomena.Here, we propose a universal theory to comprehensively describe the nature of spin textures by incorporating socksmith santa cruz three symmetry flavors of reciprocal wavevector, atomic orbital, and atomic site.

Such an approach enables us to establish a complete classification of spin textures constrained by the little co-group miracle academy clothing and predict some exotic spin texture types, such as Zeeman-type spin splitting in antiferromagnets and quadratic spin texture.To illustrate the influence of atomic orbitals and sites on spin textures, we predict orbital-dependent spin texture and anisotropic spin-momentum-site locking effects, and corresponding material candidates validated through first-principles calculations.The comprehensive classification and the predicted new spin textures in realistic materials are expected to trigger future spin-based functionalities in electronics.
