Magnetic Skyrmion Interacting with Optical Skyrmion
Lan Bo, Jian Chen, Xichao Zhang +3
Magnetic skyrmions (MSks) and optical skyrmions (OSks) embody topology in matter and in light, respectively. Here we investigate the interaction between a single MSk and an OSk bea…
Janus skyrmion: Interfacial quasiparticle with two-faced helicity
Xichao Zhang, Rui Zhang, Qiming Shao +4
Janus particles are functional particles with at least two surfaces showing asymmetric properties. We show at the interface between two magnetic regions with different antisymmetri…
All-electric control of skyrmion-bimeron transition in van der Waals heterostructures
Lan Bo, Songli Dai, Xichao Zhang +4
Two-dimensional van der Waals materials offer a versatile platform for manipulating atomic-scale topological spin textures. In this study, using first-principles and micromagnetic…
Diffusion asymmetry of repulsive skyrmions in structured environment
Xichao Zhang, Charles Reichhardt, Cynthia J. O. Reichhardt +5
The diffusion of matter in structured environments can give rise to emergent phenomena that do not occur in unstructured environments. Here, we report the asymmetric diffusion of m…
Bimerons create bimerons: proliferation and aggregation induced by currents and magnetic fields
Xichao Zhang, Yan Zhou, Xiuzhen Yu +1
The aggregation of topological spin textures at nano and micro scales has practical applications in spintronic technologies. Here, the authors report the in-plane current-induced p…
Transformation of a cellular skyrmion to polyomino-like structures
Jing Xia, Xichao Zhang, Yan Zhou +3
Topological spin structures with transformable shapes may have potential implications on data storage and computation. Here, we demonstrate that a square cellular skyrmion on an ar…
Suppression of the skyrmion Hall effect in synthetic ferrimagnets with gradient magnetization
Lan Bo, Xichao Zhang, Masahito Mochizuki +1
Magnetic skyrmions are promising building blocks for future spintronic devices. However, the skyrmion Hall effect (SkHE) remains an obstacle for practical applications based on the…
Magnon-Skyrmion Hybrid Quantum Systems: Tailoring Interactions via Magnons
Xue-Feng Pan, Peng-Bo Li, Xin-Lei Hei +4
Coherent and dissipative interactions between different quantum systems are essential for the construction of hybrid quantum systems and the investigation of novel quantum phenomen…
Global Rotation of Skyrmion Bags under Vertical Microwave Fields
Lan Bo, Rongzhi Zhao, Xichao Zhang +2
Magnetic skyrmion bags are composite topological spin textures with arbitrary topological charges. Here, we computationally study the transient rotational motion of skyrmion bags,…
Predicted Multiple Walker Breakdowns for Current-Driven Domain-Wall Motion in Antiferromagnets
Mu-Kun Lee, Rubén M. Otxoa, Masahito Mochizuki
We theoretically discover possible emergence of reentrant Walker breakdowns for current-driven domain walls in layered antiferromagnets in striking contrast to the unique Walker br…
Handwritten Digit Recognition by Spin Waves in a Skyrmion Reservoir
Mu-Kun Lee, Masahito Mochizuki
By performing numerical simulations for the handwritten digit recognition task, we demonstrate that a magnetic skyrmion lattice confined in a thin-plate magnet possesses high capab…
Chiral Skyrmions Interacting with Chiral Flowers
Xichao Zhang, Jing Xia, Oleg A. Tretiakov +5
The chiral nature of active matter plays an important role in the dynamics of active matter interacting with chiral structures. Skyrmions are chiral objects, and their interactions…
Hall effect of spin-chirality origin in a triangular-lattice helimagnet Fe1.3Sb
Y. Shiomi, M. Mochizuki, Y. Kaneko +1
We report on a topological Hall effect possibly induced by scalar spin chirality in a quasi-two- dimensional helimagnet FeSb. In the low-temperature region where the spins…
