High-order concentric hopfions in a helimagnet
Konstantin L. Metlov, Maksim M. Gordei
Magnetic hopfions are three-dimensional topological solitons: ``knots'' in the vector field of magnetization of magnetically ordered materials, which are a key element of the three…

Spatial decay of isolated magnetic hopfions in chiral helimagnets
Konstantin L. Metlov, Maksim M. Gordei
Magnetic hopfions in chiral magnets are topological solitons, localized in three dimensions. But is their localization strong? To address this question we derive an asymptotic expa…

Control of the magnetic hopfion lattice in helimagnet with the external field and anisotropy
Konstantin L. Metlov, Artem S. Tarasenko, Yulia A. Bezus +1
A generalized micromagnetic model of hopfions in a helimagnet with a two-dimensional (allowing both radial and azimuthal dependence) profile function is considered. Calculations co…
