First-principles Dzyaloshinskii-Moriya interaction in a non-collinear framework
R. Cardias, A. Szilva, M. M. Bezerra-Neto +7
We have derived an expression of the Dzyaloshinskii-Moriya (DM) interaction, where all the three components of the DM vector can be calculated independently, for a general, non-col…
Interatomic exchange interactions in non-collinear magnets
A. Szilva, M. Costa, A. Bergman +3
We derive ab inito exchange parameters for general non-collinear magnetic configurations, in terms of a multiple scattering formalism. We show that the general exchange formula has…
Higher-order contributions to the Rashba-Bychkov effect with application to Bi/Ag(111) surface alloy
Sz. Vajna, E. Simon, A. Szilva +3
In order to explain the anisotropic Rashba-Bychkov effect observed in several metallic surface-state systems, we use k.p perturbation theory with a simple group-theoretical analysi…
Exchange interaction between magnetic adatoms on surfaces of noble metals
E. Simon, B. Ujfalussy, B. Lazarovits +3
We present first principles calculations of the exchange interactions between magnetic impurities deposited on (001), (110) and (111) surfaces of Cu and Au and analyze them, in par…
