WebApr 3, 2024 · Dzyaloshinskii–Moriya (DM) interactions cause many interesting physical features, such as topologically nontrivial magnetic skyrmions and chiral domain walls. These interactions become more pronounced in low-dimensional systems. We investigated a one-dimensional Heisenberg spin-1/2 chain with an asymmetric DM interaction. WebApr 11, 2024 · We studied the impact of He + irradiation on the Dzyaloshinskii–Moriya interaction (DMI) in Ta/Co 20 Fe 60 B 20 /Pt/MgO samples. We found that irradiation of 40 keV He + ions increases the DMI by approximately 20% for fluences up to 2 × 10 16 ions/cm 2 before it decreases for higher fluence values.
