      abstract     = {The Dzyaloshinskii-Moriya interaction (DMI) has drawn much
                      attention, as it stabilizes magnetic chirality, with
                      important implications in fundamental and applied research.
                      This antisymmetric exchange interaction is induced by the
                      broken inversion symmetry at interfaces or in
                      noncentrosymmetric lattices. Significant interfacial DMIs
                      are often found at magnetic/heavy-metal interfaces with
                      large spin-orbit coupling. Recent studies have shown promise
                      for induced DMI at interfaces involving light elements such
                      as carbon (graphene) or oxygen. Here, we report direct
                      observation of induced DMI by chemisorption of the lightest
                      element, hydrogen, on a ferromagnetic layer at room
                      temperature, which is supported by density functional theory
                      calculations. We further demonstrate a reversible chirality
                      transition of the magnetic domain walls due to the induced
                      DMI via hydrogen chemisorption and desorption. These results
                      shed new light on the understanding of DMI in low atomic
                      number materials and the design of novel chiral spintronics
                      and magneto-ionic devices.},
