Attractive Hopfions and Bimerons in Thin Films of Chiral Magnets: Cluster Formation and Lattice Instability in the Conical Phase
Andrey O. Leonov, Takayuki Shigenaga
We investigate the energetics, interactions, and ordering tendencies of bimerons (cholesteric fingers of the second type, CF--2) and hopfions in thin films of chiral magnets and ch…

Cholesteric Fingers from a Magnetic Perspective: Topology, Energetics, and Interactions
Takayuki Shigenaga, Andrey O. Leonov
Chiral liquid crystals and chiral magnets host a wide variety of topological solitons described by closely related continuum theories, namely the Frank-Oseen and Dzyaloshinskii mod…

Confinement-Induced Metastability and Structural Diversity of Hopfions in Chiral Magnetic Films
Andrey O. Leonov, Takayuki Shigenaga
Topological particle-like excitations such as skyrmions and hopfions offer rich opportunities for spintronic and photonic applications. While skyrmions have been extensively studie…
