  The realization of topological antiferromagnetic (AFM) solitons in real
materials is a major goal towards their use in information technology. While
they 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, frustrated
multimeronic spin-textures hosted by a N\'eel magnetic state, arising in single
Mn layers directly grown on Ir(111) surface or interfaced with Pd-based films.
These 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 N\'eel AFM multimerons as exciting
highly-sought after AFM solitons having the potential to be utilized in novel
spintronic devices hinging on non-synthetic AFM quantum materials.
