Domain-wall skyrmion chain and domain-wall bimerons in chiral magnets

Friday, 18 April, 2025 - 15:44
Yuki Amari, Calum Ross, and Muneto Nitta We construct domain-wall skyrmion chains and domain-wall bimerons in chiral magnets with an out-of-plane easy-axis anisotropy and without a Zeeman term coupling to a magnetic field. Domain-wall skyrmions are skyrmions trapped inside a domain wall, and they are present in the ferromagnetic (FM) phase of …
