Curvature-induced emergence of a second critical field for domain wall dynamics in bent nanostripes (2021)
Bittencourt, G. H.R.; Moreno, Roberto; Cacilhas, R.; Castillo-Sepúlveda, Sebastian; Chubykalo-Fesenko, O.; Altbir, Dora; Carvalho-Santos, Vagson Luiz (American Institute of Physics Inc., 2021-04-05)We investigate the dynamics of a transverse domain wall (DW) in a bent nanostripe under an external field and spin-polarized current. Besides the standard Walker breakdown phenomenon, we show the emergence of a second ... -

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 ...
