Abstract: The effect of irradiation with helium ions of thin cobalt films on a layer of heavy metals (Pt and W) on the interfacial Dzyaloshinskii–Moriya interaction (iDMI) is studied experimentally. The iDMI value is measured via Brillouin light scattering (BLS). The hysteresis loops of the samples are measured via optical magnetometry. The iDMI value varies nonmonotonically in the range of 0.1–0.6 J m $^{-2}$ at fluences of 10$^{14}$–10$^{16}$ cm$^{-2}$.
Keywords: ferromagnetic films, Dzyaloshinskii–Moriya surface interaction, perpendicular anisotropy.
