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…
Reversible to Irreversible Transitions for ac Driven Skyrmions on Periodic Substrates
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
Using atomistic simulations, we investigate the dynamical behavior of magnetic skyrmions in dimer and trimer molecular crystal arrangements, as well as bipartite lattices at 3/2 an…
Skyrmion Molecular Crystals and Superlattices on Triangular Substrates
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
Using atomistic simulations, we show that new types of skyrmion states called skyrmion molecular crystals and skyrmion superlattices can be realized on triangular substrates when t…
Shapiro Steps and Stability of Skyrmions Interacting with Alternating Anisotropy Under the Influence of ac and dc Drives
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
We use atomistic simulations to examine the sliding dynamics of a skyrmion in a two-dimensional system containing a periodic one-dimensional stripe pattern of variations between lo…
Skyrmion Transport and Annihilation in Funnel Geometries
F. S. Rocha, J. C. Bellizotti Souza, N. P. Vizarim +3
Using atomistic simulations, we have investigated the transport and annihilation of skyrmions interacting with a funnel array under a current applied perpendicular to the funnel ax…
