Emergence of zero-field non-synthetic single and interchained antiferromagnetic skyrmions in thin films

Abstract

An intrinsic antiferromagnetic skyrmion is located entirely within a single atomic layer, rather than two coupled layers. Here, the authors predict the existence of intrinsic antiferromagnetic skyrmions in a chromium monolayer deposited on a PdFe/Ir(111) substrate, which can form interlinked chain structures.
