Planar Interfaces for Transmission of Chiral Spin Textures
Robin Msiska, Cynthia J. O. Reichhardt, Charles Reichhardt +2
Lateral magnetic interfaces provide a direct way to test whether skyrmions remain robust when driven across abrupt changes in material parameters and magnetic order. Here we study…
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…
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…
Diode Effect for Skyrmions Interacting with Linear Protrusion Defects
J. C. Bellizotti Souza, C. J. O. Reichhardt, C. Reichhardt +2
We simulate collectively interacting skyrmions in a channel with periodic asymmetry, and find a strong diode effect for the skyrmion flow. There is also an asymmetry in the skyrmio…
Sliding Dynamics of Skyrmion Molecular Crystals
J. C. Bellizotti Souza, C. J. O. Reichhardt, C. Reichhardt +2
Using both atomistic and particle-based simulations, we investigate the current-driven dynamics of skyrmions on two-dimensional periodic substrates when there are multiple skyrmion…
Skyrmionium Dynamics and Stability on One Dimensional Anisotropy Patterns
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
We examine a skyrmionium driven over a periodic anisotropy pattern, which consists of disorder free regions and disordered regions. For small defect densities, the skyrmionium flow…
