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…

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, )…

Communicating skyrmions as the main mechanism underlying skyrmionium (meta)stability in quasi-two-dimensional chiral magnets
Kaito Nakamura, Andrey O. Leonov
We re-examine the internal structure of skyrmioniums stabilized in quasi-two-dimensional chiral magnets with easy-axis uniaxial anisotropy. Skyrmioniums are particle-like states of…
