    • 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, ...
    • Magnetostatic interaction between two bubble skyrmions 
      Castro, M. A.; Mancilla Almonacid, D.; Valdivia Hepp, Juan Alejandro; Allende, S. (IOP, 2020)
      A detailed analytic and numerical analysis of the interaction between two bubble skyrmions has been carried out. The results from the micromagnetic calculations show that when the skyrmions are in the same plane, the ...
    • Magnon valley Hall effect in CrI3-based van der Waals heterostructures 
      Hidalgo Sacoto, R.; González, R. I.; Vogel, E. E.; Allende, S.; Mella Riquelme, José; Cárdenas Valencia, Carlos; Troncoso, Robert E.; Muñoz Sáez, Francisco (American Physical Society, 2020)
      Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ...
    • Polycrystalline Ni nanotubes under compression: a molecular dynamics study 
      Rojas Núñez, J.; Baltazar, S. E.; González, R. I.; Bringa, E. M.; Allende, S.; Kiwi, M.; Valencia, F. J. (Nature, 2020)
      Mechanical properties of nanomaterials, such as nanowires and nanotubes, are an important feature for the design of novel electromechanical nano-architectures. Since grain boundary structures and surface modifications can ...
    • 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 ...
    • Ultrafast domain wall propagation due to the interfacial Dzyaloshinskii-Moriya interaction 
      Mancilla Almonacid, D.; Jaeschke Ubiergo, R.; Núñez, A.; Allende, S. (IOP Publishing, 2020)
      It is shown that the interplay between curvature and interfacial Dzyalonshinsky-Moriya interaction (DMI) is a pathway to ultrafast domain wall (DW) dynamics in ferromagnetic nanotubes. In this work, we theoretically study ...
