Three-dimensional toroidal precession solitons with a nonzero Hopf index, which uniformly move along the anisotropy axis in a uniaxial ferromagnet, have been found. The structure and existence region of the solitons have been numerically determined by solving the Landau-Lifshitz equation.

Static Hopf Solitons and Knotted Emergent Fields in Solid-State Noncentrosymmetric Magnetic Nanostructures.
TLDR
This work model the existence of such static solitons with different Hopf index values in noncentrosymmetric solid magnetic nanostructures with a perpendicular interfacial magnetic anisotropy and shows how this surface an isotropy, along with the Dzyaloshinskii-Moriya interactions and the geometry of nanostructure, stabilize hopfions.
Hopfion dynamics in chiral magnets
Resonant spin dynamics of topological spin textures are correlated with their topological nature, which can be employed to understand this nature. In this study, we present resonant spin dynamics of…

Self-assembly and electrostriction of arrays and chains of hopfion particles in chiral liquid crystals
TLDR
It is reported that three-dimensional skyrmions in the form of double-twist tori called ‘hopfions’, or ‘torons’ when accompanied by additional self-compensating defects, self-assemble into periodic arrays and linear chains that exhibit electrostriction in confined chiral nematic liquid crystals.

Skyrmions are knot-like topologically-protected objects of use in data storage and low-energy smart devices. They can be generated by applying a magnetic field to certain chiral ferromagnets, with…
Linked topological colloids in a nematic host
TLDR
This work fabricates colloidal microparticle analogs of the classic examples of links studied in the field of topology, the Hopf and Solomon links, which are dispersed in nematic fluids that possess orientational ordering of anisotropic rod-like molecules.
