Observation of the sliding mode of the magnetic texture in Fe/Ir(111) — •Wulf Wulfhekel¹, Hung-Hsiang Hang¹, Louise Desplat², Volodymyr Kravchuk¹, Marie Hervé³, Timofey Balashov⁴, Philipp Markus¹, Markus Garst¹, and Bertrand Dupé⁵ — ¹Karlsruhe Institute of Technology, Karlsruhe — ²IPCMS, Université de Strasbourg, Strasbourg — ³Université Sorbonne, Paris — ⁴RWTH Aachen, Aachen — ⁵Université de Liège, Liège

The fourfold non-collinear spin texture of Fe on the sixfold surface of Ir(111) is known to be incommensurate along one of the diagonals of the unit cell, while it is commensurate along the other. As the periodicity of the spin texture is only a few atoms, the magnetic energy of the structure experiences the atomic lattice rather strongly. Theoretically, the sliding mode of the spin texture with respect to the crystal lattice becomes gapped in the commensurate direction while it stays soft along the incommensurate one. We report on a combined theoretical and experimental study of the sliding mode along the soft direction excited by microwave fields in the junction of a spin-polarized STM.
