      abstract     = {Skyrmions are particle-like spin textures that arise from
                      spin spiral states in the presence of an external magnetic
                      field. These spirals can originate from either frustrated
                      Heisenberg exchange interactions or the interplay between
                      exchange interactions and the relativistic
                      Dzyaloshinskii-Moriya interaction, leading to atomic- and
                      mesoscale textures, respectively. However, the conversion of
                      exchange-stabilized spin spirals into skyrmions typically
                      requires magnetic fields that exceed practical laboratory
                      limits. Here, we demonstrate a strategy leveraging hydrogen
                      adsorption to expand the range of magnetic films capable of
                      hosting stable or metastable skyrmions. In a structurally
                      open and anisotropic system of two pseudomorphic Fe layers
                      on Ir(110), spin-polarized scanning tunneling microscopy
                      combined with ab initio calculations reveals that a
                      right-handed, exchange- stabilized N´eel-type spin spiral
                      propagating along the [110] direction with a 1.3 nm period
                      transitions upon hydrogen adsorption to a
                      Dzyaloshinskii-Moriya type spiral with a sevenfold longer
                      period of 8.5 nm. This transition enables elliptical
                      skyrmions to form at moderate magnetic fields.Hydrogenation
                      thus provides a non-volatile mechanism to toggle between
                      distinct magnetic states, offering a versatile platform for
                      controlling spin textures.},
