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…
Nambu monopoles interacting with lattice defects in two-dimensional artificial square spin ice
R. C. Silva, R. J. C. Lopes, L. A. S. Mól +3
The interactions between an excitation (similar to a pair of Nambu monopoles) and a lattice defect are studied in an artificial two-dimensional square spin ice. This is done by con…
Magnetic monopole and string excitations in a two-dimensional spin ice
L. A. S. Mol, R. L. Silva, R. C. Silva +3
We study the magnetic excitations of a square lattice spin-ice recently produced in an artificial form, as an array of nanoscale magnets. Our analysis, based upon the dipolar inter…
