title: Velocity asymmetry of Dzyaloshinskii domain walls in the creep and flow regimes
---

Chiral magnetic textures such as Dzyaloshinskii domain walls (DDW) [@Thiaville2012] and skyrmions [@Skyrme1960] are attracting attention because of their possible applications as information carriers in spintronics devices. DDW are Néel walls with a fixed chirality, stabilised, in non-centrosymmetric stacks, by the Dzyaloshinskii-Moriya interaction (DMI) [@Dzyaloshinskii1957; @Moriya1960] present at the interface between a magnetic layer and a heavy metal with large spin-orbit coupling. When driven by a Spin Hall effect related spin-orbit torque (SHE-SOT) [@LiuPRL2012; @Haazen2013; @Garello2013] DDW in systems with perpendicular magnetic anisotropy (PMA) move
