Direct observation of magnetic monopole freedom in two-dimensional artificial spin ice

D. G. Duarte, L. B. de Oliveira, F. S. Nascimento +4

Magnetic monopole unpairing as a function of external magnetic fields is presented as a fingerprint of this emergent quasiparticles freedom in a two-dimensional artificial spin ice…

Is there any Nambu monopolium out there?

D. O. R. Azevedo, M. L. Bispo, O. M. Del Cima +2

Magnetic monopoles have been a subject of study for more than a century since the first ideas by A. Vaschy and P. Curie, circa 1890. In 1974, Y. Nambu proposed a model for magnetic…

Robust dynamics of antiferromagnetic skyrmion driven by spin-polarized current in small thin disks

R. L. Silva, R. C. Silva, W. A. Moura-Melo +1

We investigate skyrmion configuration and dynamics in antiferromagnetic thin disks. It is shown that the skyrmion acquires oscillatory dynamics with well-defined amplitude and freq…

Typical skyrmions versus bimerons: a long-distance competition in ferromagnetic racetracks

A. S. Araújo, R. J. C. Lopes, V. L. Carvalho-Santos +4

During the last years, topologically protected collective modes of the magnetization have called much attention. Among these, skyrmions and merons have been the object of intense s…

Topological Hall effect induced Skyrmion-Antiskyrmion coupling in inhomogeneous racetrack

R. C. Silva, R. L. Silva, A. R. Pereira

In this paper we investigate a magnetic racetrack consisting of a junction of three materials with different properties. Indeed, this magnetic system is composed by two distinct re…

Naked-eye visualization of geometric frustration effects in macroscopic spin ices

R. S. Gonçalves, A. C. C. Gomes, R. P. Loreto +4

We study planar rectangular-like arrays composed by macroscopic dipoles (magnetic bars with size around a few centimeters) separated by lattice spacing a and b along each direction…
