Hopfion rings in a cubic chiral magnet.

ABSTRACT: Magnetic skyrmions and hopfions are topological solitons¹-well-localized field configurations that have gained considerable attention over the past decade owing to their unique particle-like properties, which make them promising objects for spintronic applications. Skyrmions^2,3 are two-dimensional solitons resembling vortex-like string structures that can penetrate an entire sample. Hopfions^4-9 are three-dimensional solitons confined within a magnetic sample volume and can be considered as closed twisted skyrmion strings that take the shape of a ring in the simplest case. Despite extensive research on magnetic skyrmions, the direct observation of magnetic hopfions is challenging¹⁰ and has only been reported in a synthetic material¹¹. H
