Antiferromagnetic (AFM) skyrmions are envisioned as ideal localized topolo-gical magnetic bits in future information technologies. In contrast to ferro-magnetic (FM) skyrmions, they are immune to the skyrmion Hall effect, mightoffer potential terahertz dynamics while being insensitive to external magneticfields and dipolar interactions. Although observed in synthetic AFM structuresand as complex meronic textures in intrinsic AFM bulk materials, their reali-zation in non-synthetic AFM films, of crucial importance in racetrack concepts,has been elusive. Here, we unveil their presence in a row-wise AFM Cr filmdeposited on PdFe bilayer grown on fcc Ir(111) surface. Using first principles,we demonstrate the emergence of single and strikingly interpenetrating chainsof AFM skyrmions, which can co-exist with the rich inhomogeneous exchangefield, including that of FM skyrmions, hosted by PdFe. Besides the identifica-tion of an ideal platform of materials for intrinsic AFM skyrmions, we antici-pate the uncovered knotted solitons to be promising building blocks in AFMspintronics. |
