      Nucleation and Stability of Toron Chains in Non-Centrosymmetric Magnetic Nanowires (2024) 

      Castillo-Sepúlveda, Sebastián; Corona, Rosa M.; Saavedra, Eduardo; Laroze, David; Espejo, Alvaro P.; Carvalho-Santos, Vagson L.; Altbir, Dora (MDPI, 2023)
      This work analyzes the magnetic configurations of cylindrical nanowires with a bulk Dzyaloshinskii–Moriya interaction and easy-plane anisotropy. We show that this system allows the nucleation of a metastable toron chain ...

      Skyrmion Dynamics in a Double-Disk Geometry under an Electric Current (2024) 

      Castillo-Sepúlveda, Sebastián; Vélez, Javier A.; Corona, Rosa M.; Carvalho-Santos, Vagson L.; Laroze, David; Altbir, Dora (MDPI, 2022)
      In this work, we present an analysis of skyrmion dynamics considering Dzyaloshinskii–Moriya interactions in an STNO device with a double-disk geometry. Three regimes were observed as a function of geometric parameters and ...

      Skyrmion Dynamics in a Double-Disk Geometry under an Electric Current: Part Two (2024) 

      Castillo-Sepúlveda, Sebastián; Vélez, Javier A.; Corona, Rosa M.; Carvalho-Santos, Vagson L.; Laroze, David; Altbir, Dora (MDPI, 2022)
      Using numerical simulations, we studied the dynamics of two skyrmions nucleated in a double-disk structure. Depending on the geometry and the electric current, different regimes for the dynamical behavior of the skyrmions ...
