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…

Comparing Dynamics, Pinning and Ratchet Effects for Skyrmionium, Skyrmions, and Antiskyrmions

J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2

We compare the driven dynamics of skyrmions, antiskyrmions, and skyrmionium interacting with random disorder, circular defects, and asymmetric potentials. When interacting with a l…

Soliton motion induced along ferromagnetic skyrmion chains in chiral thin nanotracks

J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2

Using atomistic magnetic simulations we investigate the soliton motion along a pinned skyrmion chain containing an interstitial skyrmion. We find that the soliton can exhibit stabl…
