      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 ...

      Magnetic hopfions in toroidal nanostructures driven by an Oersted magnetic field (2021) 

      Castillo-Sepúlveda, Sebastian; Cacilhas, R.; Carvalho-Santos, Vagson Luiz; Corona, Rosa M.; Altbir, Dora (American Physical Society, 2021-11-01)
      The search for magnetic hopfions has been the focus of intense research during the last years. In this direction, and using micromagnetic simulations, we studied the magnetization reversal mechanism in toroidal nanoparticles ...
