      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 a 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-principles
                      simulations predict their emergence in an intrinsic form,
                      within an row-wise AFM single monolayer of Cr deposited on
                      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 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.},
