Vortices, characterized by circular in-plane magnetization (chirality) and out-of-plane core polarization, naturally arise in confined geometries due to the interplay between exchange and dipolar interactions. In contrast, skyrmions typically require the Dzyaloshinskii-Moriya interaction for stabilization and exhibit fixed chirality-polarity relationships. Through micromagnetic simulations, we reveal that these seemingly distinct topological states can coexist, forming a novel composite state termed the \\textit{n}-skyrmion vortex, which represents a skyrmion-embedded vortex state. These composite states possess quantized topological charges $Q$ that follow the relation $Q_{\\text{total}} = Q_{\\text{vortex}} + nQ_{\\text{skyrmion}}$, where $n$ denotes the number of embedded skyrmions. Similar to vortices, these states exhibit independent chirality and polarity and are energetically degenerate.","url_abs":"https://arxiv.org/abs/2503.16078v1","url_pdf":"https://arxiv.org/pdf/2503.16078v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"magnetic-skyrmions-embedded-in-a-vortex","repo_url":"https://github.com/ww1g11/skyrmions-embedded-in-a-vortex","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
