Abstract: Skyrmions are topologically protected spin textures that are envisioned to be the next generation of bits. However, conventional ferromagnetic (FM) skyrmions are deflected when an electric field is applied, which limits optimal implementation in future spintronic devices. In contrast, antiferromagnetic (AFM) skyrmions, which consist of two FM solitons coupled antiferromagnitically, are predicted to have zero net magnus force , and this makes them promising candidates for spintronic racetrack memories. So far these have been stabilized in synthetic AFM structures , i.e.multilayers hosting FM skyrmions, which couple antiferromagnetically through a non-magnetic spacer. Here, based on density functional theory (DFT) in conjunction with atomistic spin dynamics, we investigate systematically and predict the presence of chiral intrinsic AFM structures in specific and realistic combination of thin films of Cr/Pd/Fe deposited on heavy substrates composed of Ir(111) on triangular lattice, with fcc stacking.
