Metallic islands in the Kondo insulator SmB
J. C. Souza, P. F. S. Rosa, J. Sichelschmidt +7
The predicted interplay between Kondo physics and non-trivial topology in SmB has stimulated many experimental reports, some of which are in apparent contradiction. The origi…
Guided Skyrmion Motion Along Pinning Array Interfaces
N. P. Vizarim, C. Reichhardt, P. A. Venegas +1
We examine ac driven skyrmions interacting with the interface between two different obstacle array structures. We consider drive amplitudes at which skyrmions in a bulk obstacle la…
Skyrmion Pinball and Directed Motion on Obstacle Arrays
N. P. Vizarim, C. J. O. Reichhardt, P. A. Venegas +1
We examine skyrmions interacting with a square array of obstacles under ac drives applied in one or two directions. For a single direction of ac driving, we find that the Magnus fo…
Skyrmion Dynamics and Transverse Mobility: Skyrmion Hall Angle Reversal on 2D Periodic Substrates with dc and Biharmonic ac Drives
N. P. Vizarim, C. J. O. Reichhardt, P. A. Venegas +1
We numerically examine the dynamics of a skyrmion interacting with a two-dimensional periodic substrate under dc and biharmonic ac drives. We show that the Magnus force of the skyr…
Shapiro Steps and Nonlinear Skyrmion Hall Angles For dc and ac Driven Skyrmions on a Two Dimensional Periodic Substrate
N. P. Vizarim, C. Reichhardt, P. A. Venegas +1
For an overdamped particle moving over a two-dimensional periodic substrate under combined dc and ac drives, a series of steps can appear in the velocity force curves that are know…
