Since structural inversion asymmetry (SIA) is required for their stability, the observation of chiral domain walls in highly symmetric Pt/Co/Pt is intriguing. Here, we tune the layer asymmetry in this system and observe, by current-assisted DW depinning experiments, a small chiral field which sensitively changes. Moreover, we convincingly link the observed efficiency of DW motion to the DW texture, using DW resistance as a direct probe for the internal orientation of the DW under the influence of in-plane fields. The very delicate effect of capping layer thickness on the chiral field allows for its accurate control, which is important in designing novel materials for optimal spin-orbit-torque-driven DW motion.Scientific reports5248https://www.ebi.ac.uk/biostudies/studies/S-EPMC4052744biostudies-literatureTunable chiral spin texture in magnetic domain-walls.PMC4052744Herps MFranken JHKoopmans BSwagten HJfalseTunable chiral spin texture in magnetic domain-walls.Magnetic domain-walls (DWs) with a preferred chirality exhibit very efficient current-driven motion.
