    • 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 ...
    • Energetics and the magnetic state of Mn2 adsorbed on Au(111): Dimer bond distance dependence 
      López Moreno, S.; Mejía López, J.; Muñoz Sáez, Francisco; Calles, A.; Morán López, J. L. (Elsevier, 2016)
      In this work we present a theoretical study of the adsorption Mn-2 dimer on the Au(111) surface. Here we use the density functional theory to construct a map of adsorption energies, E-A, of Mn-2 on a Au(111) surface as a ...
    • Surface states of FeF2 (110) and its uncompensated magnetization 
      Muñoz Sáez, Francisco; Romero, A.H.; Mejía López, J.; Roshchin, Igor V.; González, R. I.; Kiwi Tichauer, Miguel (Elsevier, 2015)
      The (110) surface of iron fluoride (FeF2) is especially relevant to the understanding of the exchange bias phenomenon, which has important applications in the sensor industry, and has been extensively explored, both ...
