Curvature-induced stabilization and field-driven dynamics of magnetic hopfions in toroidal nanorings (2023)
Corona, R.M.; Saavedra, E.; Castillo-Sepulveda, S.; Escrig, J.; Altbir, D.; Carvalho-Santos, V.L. (NLM (Medline), 2023-02-09)Three dimensional magnetic textures are a cornerstone in magnetism research. In this work, we analyze the stabilization and dynamic response of a magnetic hopfion hosted in a toroidal nanoring with intrinsic Dzyaloshinskii-Moriya ... -

Domain wall damped harmonic oscillations induced by curvature gradients in elliptical magnetic nanowires (2024)
Bittencourt, G.H.R.; Castillo-Sepúlveda, S.; Chubykalo-Fesenko, O.; Moreno, R.; Altbir, D.; Carvalho-Santos, V.L. (American Physical Society, 2022)This paper focuses on the dynamics of a domain wall (DW) displacing along an elliptically bent nanowire (NW) under the action of spin-polarized electric currents and external magnetic fields. Our results evidence that a ... -

Dzyaloshinskii-Moriya bias in a free-standing asymmetric homogeneous nanodisk (2024)
Castillo-Sepúlveda, S.; Corona, R.M.; Kiwi, M.; Carvalho-Santos, V.L.; Altbir, D. (Elsevier B.V., 2024)An off-center shift of the magnetic hysteresis loop, usually known as exchange bias, develops in an asymmetric nanodisk due to the Dzyaloshinskii-Moriya (DM) interaction. Results exhibit the onset of bias in a system without ... -

Symmetry-dependent domain wall propagation in triangular nanowires (2024)
Corona, R.M.; Carvalho-Santos, V.L.; Castillo-Sepúlveda, S.; Altbir, D. (Elsevier B.V., 2024)Magnetic domain walls (DW) are interesting for several technologies requiring perfect control of their propagation along a nanostructure. Therefore, it is necessary to better understand their dynamics. In this paper, using ...
