The exchange coupling between the valence electrons of the fullerene cage and the electrons of the N atoms in N@C60^{-1,3}
L. Udvardi
MCSCF calculations are performed in order to determine the exchange coupling between the 2p electrons of the N atom and the LUMOs of the fullerene cage in the case of mono- and tri…

Giant magnetic anisotropy of the bulk antiferromagnets IrMn and IrMn3
L. Szunyogh, B. Lazarovits, L. Udvardi +2
Theoretical predictions of the magnetic anisotropy of antiferromagnetic materials are demanding due to a lack of experimental techniques which are capable of a direct measurement o…

First principles calculation of spin-interactions and magnetic ground states of Cr trimers on Au(111)
A. Antal, B. Lazarovits, L. Udvardi +3
We present calculations of the magnetic ground states of Cr trimers in different geometries on top of a Au(111) surface. By using a least square fit method based on a fully relativ…
