Facilitating domain wall injection in magnetic nanowires by electrical means
Davi R. Rodrigues, Nils Sommer, Karin Everschor-Sitte
We investigate how to facilitate the injection of domain walls in chiral ferromagnetic nanowires by electrical means. We calculate the critical current density above which domain w…
Spin-transfer torque-driven motion, deformation, and instabilities of magnetic skyrmions at high currents
Jan Masell, Davi R. Rodrigues, Ben F. McKeever +1
In chiral magnets, localized topological magnetic whirls, magnetic skyrmions, can be moved by spin polarized electric currents. Upon increasing the current strength, with prospects…
Chiral excitations of magnetic droplet solitons driven by their own inertia
M. Mohseni, D. R. Rodrigues, M. Saghafi +7
The inertial effects of magnetic solitons play a crucial role in their dynamics and stability. Yet governing their inertial effects is a challenge for their use in real devices. He…
Spin eigen-excitations of an antiferromagnetic skyrmion
Volodymyr P. Kravchuk, Olena Gomonay, Denis D. Sheka +5
We theoretically predict and classify the localized modes of a skyrmion in a collinear uniaxial antiferromagnet and discuss how they can be excited. As a central result, we find tw…
Characterizing breathing dynamics of magnetic (anti-)skyrmions within the Hamiltonian formalism
B. F. McKeever, D. R. Rodrigues, D. Pinna +3
We derive an effective Hamiltonian system describing the low energy dynamics of circular magnetic skyrmions and antiskyrmions. Using scaling and symmetry arguments we model (anti-)…
