abstract = {Topological antiferromagnetism is a vibrant and captivating
research field, generating considerable enthusiasm with the
aim of identifying topologically protected magnetic states
of key importance in the hybrid realm of topology,
magnetism, and spintronics. While topological
antiferromagnetic (AFM) solitons bear various advantages
with respect to their ferromagnetic cousins, their
observation is scarce. Utilizing first-principles
simulations, here we predict new chiral particles in the
realm of AFM topological magnetism, exchange-frustrated
multimeronic spin textures hosted by a Néel magnetic state,
arising universally in single Mn layers directly grown on an
Ir(111) surface or interfaced with Pd-based films. These
nanoscale topological structures are intrinsic; i.e. they
form in a single AFM material, can carry distinct
topological charges, and can combine in various multimeronic
sequences with enhanced stability against external magnetic
fields. We envision the frustrated Néel AFM multimerons as
exciting highly sought after AFM solitons having the
potential to be utilized in novel spintronic devices hinging
on nonsynthetic AFM quantum materials, further advancing the
frontiers of nanotechnology and nanophysics},
