Channeling Skyrmions: suppressing the skyrmion Hall effect in ferrimagnetic nanostripes
R. C. Silva, R. L. Silva, J. C. Moreira +2
The Skyrmion Hall Effect (SkHE) observed in ferromagnetic (FM) and ferrimagnetic (FI) skyrmions traveling due to a spin-polarized current can be a problematic issue when it comes t…
Quantifying ground state degeneracy in planar artificial spin ices: the magnetic structure factor approach
F. S. Nascimento, L. B. de Oliveira, D. G. Duarte +3
Magnetic structure factor (MSF) is employed to investigate the ground state degeneracy in rectangular-like artificial spin ices. Our analysis considers the importance of nanoisland…
Creation,transport and detection of imprinted magnetic solitons stabilized by spin-polarized current
R. P. Loreto, W. A. Moura-Melo, A. R. Pereira +4
With the recent proposition of skyrmion utilization in racetrack memories at room temperature, skyrmionics has become a very attractive field. However, for the stability of skyrmio…
How hole defects modify vortex dynamics in ferromagnetic nanodisks
W. A. Moura-Melo, A. R. Pereira, R. L. Silva +1
Defects introduced in ferromagnetic nanodisks may deeply affect the structure and dynamics of stable vortex-like magnetization. Here, analytical techniques are used for studying, a…
Heisenberg model on a space with negative curvature: topological spin textures on the pseudosphere
L. R. A. Belo, N. M. Oliveira-Neto, W. A. Moura-Melo +2
Heisenberg-like spins lying on the pseudosphere (a 2-dimensional infinite space with constant negative curvature) cannot give rise to stable soliton solutions. Only fractional solu…
Geometrical pinning of magnetic vortices induced by a deficit angle on a surface: anisotropic spins on a conic space background
W. A. Moura-Melo, A. R. Pereira, L. A. S. Mol +1
We study magnetic vortex-like excitations lying on a conic space background. Two types of them are obtained. Their energies appear to be linearly dependent on the conical aperture…
