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.},
