    • Domain wall propagation tuning in magnetic nanowires through geometric modulation 

      Costa Arzuza, Luis Carlos; López Ruiz, Román; Salazar Aravena, Diego; Knobel, Marcelo; Beron, Fanny; Pirota, Kleber Roberto (Journal of Magnetism and Magnetic Materials, 2017-01-25)
      The magnetic behavior of nickel modulated nanowires embedded in porous alumina membranes is investigated. Their diameters exhibit a sharp transition between below (35 nm) and above (52 nm) the theoretical limit for transverse ...
    • Effective demagnetizing tensors in arrays of magnetic nanopillars 

      Mendoza Zelis, P; Vega, Víctor V; Prida, V M; Costa Arzuza, Luis Carlos; Beron, Fanny; Pirota, Kleber Roberto; Lopez Ruiz, Roman; Sanchez, Francisco Homero (Physical Review B, 2017-11-21)
      A model describing the effect of magnetic dipolar interactions on the susceptibility of magnetic nanopillars is presented. It is an extension of a recently reported model for three-dimensional randomlike dispersions of ...
    • Synthesis and magnetic properties of cobalt-iron/cobalt-ferrite soft/hard magnetic core/shell nanowires 

      Londoño Calderón, Cesar Leandro; Moscoso Londoño, Oscar; Muraca, Diego; Costa Arzuza, Luis Carlos; Carvalho, Peterson; Pirota, Kleber Roberto; Knobel, Marcelo; Pampillo, Laura Gabriela; Martínez García, Ricardo (Nanotechnology, 2017)
      A straightforward method for the synthesis of CoFe2.7/CoFe2O4 core/shell nanowires is described. The proposed method starts with a conventional pulsed electrodeposition procedure on alumina nanoporous template. The obtained ...
