Current-Induced Dynamics and Instability Pathways of Skyrmioniums in Chiral Magnets
Kaito Nakamura, Yuka Kotorii, Andrey O. Leonov
We present a comprehensive study of current-driven dynamics, transformations, and instabilities of skyrmioniums in chiral magnetic films, considering both isolated objects and coll…

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…

Skyrmionium meta-matter: a topologically heterogeneous magnetic crystal with emergent hybrid dynamics
Andrey O. Leonov, Kaito Nakamura
We introduce and systematically investigate a new class of topological magnetic textures, skyrmionium meta-matter, composed of skyrmioniums (Skm, ) and skyrmions (Sk, )…
