| contents | Ultrathin magnetic films on heavy metal substrates with strong spin-orbit coupling provide versatile platforms for exploring novel spin textures. So far, structurally open fcc(110) substrates remain largely terra incognita. Here, we stabilize a metastable, unreconstructed Ir(110)-$(1 \times 1)$ surface supporting two layers of Fe. Combining spin-polarized scanning tunneling microscopy and ab initio calculations, we reveal a right-handed Néel-type spin spiral along the [$\overline{1}10$] crystallographic direction with a period of 1.27~nm as the magnetic ground state. Our analysis reveals this spiral is of the Yoshimori type, i.e., driven by frustrated Heisenberg interactions, with the Dzyaloshinskii-Moriya interaction determining its cycloidal nature and handedness. |
