    • Analysis on the stability of in-surface magnetic configurations in toroidal nanoshells 
      Teixeira, A. W.; Castillo-Sepúlveda, S.; Vojkovic, S.; Fonseca, J. M.; Altbir, D.; Núñez, S.; Carvalho-Santos, V. L. (Elsevier B.V., 2019)
      Curvature of nanomagnets can be used to induce chiral textures in the magnetization field. Here we perform analytical calculations and micromagnetic simulations aiming to analyze the stability of in-surface magnetization ...
    • Magnetic cylindrical nanowires with single modulated diameter 
      Allende, S.; Altbir, D.; Nielsch, K. (2009)
      Nucleation and propagation of a domain wall along a modulated wire as a function of its geometry has been investigated. In all the cases, nucleation began at the thicker section and propagated toward the thinner section, ...
    • Spin wave modes of two magnetostatic coupled spin transfer torque nano-oscillators 
      Mancilla-Almonacid, D.; Arias, R.; Escobar, R.; Altbir, D.; Allende, S. (American Institute of Physics Inc., 2018)
      A detailed analytical and numerical study of the spin wave modes of two nanopillar spin torque nano-oscillators coupled by magnetostatic interactions is presented under the macrospin approximation. Results show that the ...
    • Synchronization of two spin-transfer-driven nano-oscillators coupled via magnetostatic fields 
      Mancilla-Almonacid, D.; Leon, Alejandro O.; Arias, R. E.; Allende, S.; Altbir, D. (American Physical Society, 2019)
      The magnetization dynamics of nano-oscillators may be excited by both magnetic fields and spin-polarized currents. While the dynamics of single oscillators has been well characterized, the synchronization of several ones ...
    • Tuning the frequencies of the normal modes of a nanopillar oscillator through the magnetostatic interaction 
      Mancilla Almonacid, D.; Arias Federici, Rodrigo; Oyarzún, S.; Altbir, D.; Allende, S. (American Physical Society, 2017)
      A detailed analytical and numerical study of the spin wave modes of the free layer of a nanopillar spin torque nano-oscillator (STNO) has been performed as a function of the magnetostatic interaction between the free and ...
    • Twisted skyrmions through dipolar interactions 
      Castillo Sepúlveda, S.; Corona, R. M.; Núñez, A. S.; Altbir, D. (Elsevier, 2019)
      The manifestations of the dipolar interaction in magnetic nano-devices can take subtle forms. In this work, we address the effects of dipolar interactions on skyrmions textures. The so-called twisted skyrmion is a natural ...
