    • Asymmetric magnetic dots: A way to control magnetic properties 
      Vargas, N. M.; Allende, S.; Leighton, B.; Escrig, J.; Mejía López, J.; Altbir, D.; Schuller, Ivan K. (AMER INST PHYSICS, CIRCULATION & FULFILLMENT DIV, 2011-04-01)
      We have used Monte Carlo simulations to investigate the magnetic properties of asymmetric dots as a function of their geometry. The asymmetry of round dots is produced by cutting off a fraction of the dot and is characterized ...
    • Dipolar-driven formation of cobalt nanoparticle chains in polyethylene films 
      Vargas, E.; Melo, W. W. M.; Allende, S.; Neumann, R. F.; Denardin, J. C.; Altbir, D.; Bahiana, M. (Elsevier, 2015)
      Using a simple method we produce polyethylene film with embedded chains of cobalt nanoparticles. The crystalline magnetic nanoparticles were synthesized through a simple chemical reduction method at room temperature using ...
