      abstract     = {Skyrmions are prospected as the potential future of data
                      storage due to their topologically protected spin
                      structures. However, traditional ferromagnetic (FM)
                      skyrmions experience deflection when driven with an electric
                      current, hindering their usage in spintronics.
                      Antiferromagnetic (AFM) skyrmions, consisting of two FM
                      solitons coupled antiferromagnetically, are predicted to
                      have zero Magnus force, making them promising candidates for
                      spintronic racetrack memories. Currently, they have been
                      stabilized in synthetic AFM structures, i.e., multilayers
                      hosting FM skyrmions, which couple antiferromagnetically
                      through a non-magnetic spacer, while recent first-principle
                      simulations predict their emergence in an intrinsic form,
                      within a row-wise AFM single monolayer of Cr deposited on a
                      PdFe bilayer grown on Ir (111) surfaces. The latter material
                      forms a triangular lattice, where single and interlinked AFM
                      skyrmions can be stabilized. Here, we explore the minimal
                      Heisenberg model, enabling the occurrence of such AFM
                      solitons and the underlying phase diagrams by accounting for
                      the interplay between the Dzyaloshinskii–Moriya and
                      Heisenberg exchange interactions, as well as the magnetic
                      anisotropy and impact of the magnetic field. By providing
                      the fundamental basis to identify and understand the
                      behavior of intrinsic AFM skyrmions, we anticipate our model
                      to become a powerful tool for exploring and designing new
                      topological magnetic materials to conceptualize devices for
                      AFM spintronics.},
