Disentangling orbital and spin textures of surface-derived states in non-symmorphic semimetal HfSiS
We have investigated the spin polarization and orbital configuration of the spin-split surface states in a non-symmorphic semimetal HfSiS by spin- and angle-resolved photoelectron spectroscopy using polarized tunable photons combined with detailed theoretical calculations. We have found that the surface states surrounding the ¯¯¯ X point with C 2 v symmetry exhibit an exotic unidirectional spin texture coupled with d y z orbital. The observed unidirectional spin texture is well reproduced by the theoretical calculations. Our work clarifies the significance of orbital symmetry in the manipulation of spin orientations, providing an approach to realize the persistent spin texture for the prolonged spin-coherence time in spintronic applications.
